After a bit of hiatus from the hobby, I'm jumping back in with a high-tech UNS 60S as a pond type scape. Normally one would have a nice set of images next with the initial setup. Currently mine is an empty tank and shelves of parts and equipment. I'm determined to take it slow, research each bit and have everything on hand before adding water.

I've found the in the past ~20 years there has been quite a lot of change in the hobby. So many more products available, my last high-tech tanks was T5's and Metal Halides. My have things changed.

My Plan

Tank /Stand​

UNS 60S

Lighting

Chihiros WRGB II Pro 60
Chihiros WRGB II Pro 60 Light Shade /w Mirror
Chihiros WRBG II Pro LED Light Hanging Kit
Week Aqua Arm Stand /Black (L Stand)

Filtration​

Oase BioMaster 2 Thermo 250
Oase Shutoff Valve 16/22 mm - x 2
FZone 3M Grey Tubing 16/22 mm
Stainless Steel 16/22 to 12/16 reducer
FZone 3M Grey Tubing 12/16 mm
FZone Mini Lily Pipes w/ Skimmer

I found that to use Lily pipes that fit this tank size, I'll need to use something small, hence the reduction in tubing size.

CO2​

5 LB CO2 Tank
CO2 Art Dual Stage Regulator /w Bubble Counter and Solenoid
FZone CO2 Proof Line
CO2 Check Valve
NilocG CO2 Drop Checker /w Solution
Timer
Qanvee M2 Inline CO2 Diffuser

Lucked out with CO2, found someone on Facebook Marketplace selling 2 complete CO2 systems. With full tanks, for less than the price of a new CO2 Art Regulator. Snapped them both up.

Hardscape​

Rock - Black Lava Rock
Wood - Dragon Wood

Substrate

APT S - Base layer
UNS ControBase 2L
APT Jazz Caps
UNS ControSoil Black Fine 10L
UNS Mojave Extra Fine 8L- Open areas
UNS Sequoia 3L - Accent Rocks

Plants​

Rear Middle
Hygrophila pinnatifida
Ceratopteris thalictroides
Ludwigia palustris var Super Red

Under Wood and Rock
Cryptocoryne parva var Mini
Bucephalandra (assorted varieties)

On Rock at Water Line
Micranthemum callitrichoides var Cuba

Left and Right Sides in Sand

Exotic Pleco
Red Neon Blue Eye Rainbowfish
Badis? Once plants grow in
Goby
Snails

That's the plan.

Started collecting bits in April, then found out I'd have to be in Dallas for most of May for some family matters. While in Dallas, Aquashella was in town along with an aquascaping demo of an LFS, Fish Gallery, by MJ Aquascaping of YouTube fame. Being my plan is based on the Guppy tank MJ created, I could not miss this opportunity. Learned a lot and had the opportunity to ask MJ a lot of questions.

My intention is to Dark Start, then plant.

I'm held up by the need of one part. The Week Aqua Arm Stand /Black (L Stand) base is too wide for this tank. In need of a 3 mm spacer. My neighbor, a metal shop, made me one out of ABS plastic. It works perfectly, only they made only one. I need two. My fault for not being clearer. I'll hit them up once they are back in the shop after the weekend.

More to come...

Bought a bag off Amazon. $15 for like 400ml. 2 big bags worth.

Added it to tank.
Tds spiking everyday.
From 150 to 400 tds after a week.
Thought substrate was just leeching.

I eventually just soaked the bag in RO water for a few days until the tds stopped spiking so much. Maybe I should just soak it in bleach first before use?

Hi guys,
Lots may not know me, few maybe yes, following the suggestion from @Burr740, I'm creating my first journal. Seems a very nice moment to start a thread like this, considering that the tank is still doing the Dark Start, and will be planted this week.

The tank is a ~90g 110-50-60h (I'm a metric guy).
Equipment that I own/plan to use are:
- 2 Oase Biomaster Thermo 600
- 1 Week Aqua P900 with hanging kit
- pressurized CO2 with inline kit and regulators from CO2art
- Tropica soil, 8cm front, 10-12cm mid, 15cm at the back
- 2 Lily with intake skimmer

Right now, I'm still looking around for new plants to add in this tank, I have another 20g that is stocked with lots of Rotalas and I plan to reuse the healthy one in here, but considering the size difference I need for sure new plants.

I list all the plant that I like (probably I won't buy all of them, maybe) - attachment

the plants that I already own are:
- Macrandra, orange juice, H'ra Wallichi
- Limnophila hippuridoides
- hygrophila lancea araguaia
- egeria densa and sessiflora
- nymphea red lotus
- AR rosanervig
- bacopa Caroliniana

The plant stock is already quite diverse, but I want to add some more and maybe substitute others.

for sure I want to buy both "ramosior", rotala indica and Meta, because I have lots background plant but very few front and mid.

I'm on the hunt for a stand mounted light stand for my 120p + Hyperspot L. I've found a few options, but nothing spectacular. I figured I'd ask for info/ideas before I consider startting down the DIY route with some conduit type pipe. Ultimately, I can't bring myself to mount the light from the celling only for the cord to dangle down, but based on what I'm [not] finding, I might give in. I could in theory 3d print something to maybe obscure the cord, so that may be my ultimate fall back if this turns out to be a dead end.

WeekAqua - Mounts behind the tank, which would not be my first choice, but I would be willing to settle on it. I'm not finding anyone with it in stock and it's $300 landed from Alibaba.



ADA Solar - More the look I'm going for, but they're not intended to be used with a single light for a 120p, so I'd need 2, which is noted as discontinued (and $600 for a light stand sounds nuts)



ADA Solar Stand Option 2 - $729 + shipping just seems outrageous, even if it were in stock!


Liti Light Stand - Definitely the closest to the look I had in my mind. Seeing this made me wonder if a single 10 foot 1/2 tube of aluminum conduit could be bent in the same fashion of the multiple pieces of this stand (bending inspiration video here).

Welcome to ScapeCrunch, @Rand0mgirl!
We would love to get to know you. Please tell us about yourself. What tank do you have?

It's Christmas morning and the gift-receiving is coming to an end. What hobby-related gifts (if any) did you receive this holiday season?

Please share!

No aquarium gear for me this year but I did get a snazzy pair of shoes!

I've been consuming tons of information from this amazing forum and decided its time to start my own journal.
One, to get constructive criticism/suggestions on how to improve which would be most welcome and two, just to show other approaches to starting a new tank as everyone thinks a bit differently and to see other peoples perspective.

I only started using pressurised CO2 about 18 months ago so haven't been in the hobby that long.

The first pic below was of said attempt starting with CO2. The other reason for showing that tank is I'm using the same physical tank and also starting off the new setup with plants from that tank.

Speaking of the tank, as you will see in the first pic of the new build it is an old second hand rimmed tank with less than stellar glass. In my list of planned upgrades one of them will be to order a low iron rimless tank so I can actually appreciate what's inside it. I can never get a photo to show a clear shot of the tank. Its not a great tank but it is definitely clearer than what the photos show. I think the camera really highlights how crappy the glass is lol.

No direct inspiration here apart from including a reasonable amount of hardscape and probably having a more nature style tank, so not so formal.

I've had a large piece of driftwood hanging around that I've wanted to use in a scape. I've used it previously in a larger tank but was a fish only tank. I do know after a year submerged (tied down) it still went straight to the top when released/untied so is basically unsinkable. Not sure of the type of wood though.

I also cut it in half depth wise as it was too large for a 4 foot tank.
After trying to glue it to rocks around it etc I filled the tank...and of course all went to hell. The driftwood wanted to get to the surface so bad it broke away from the glue LOL. So I had to start the scape with a large rock sitting on it and the driftwood in a different position from where it started. Temporary at first but now I plan to cover the rock with epiphytes etc so it should be ok eventually, just not so much right now. One of those it is what it is. I'm only playing around here anyways.

I'll also say, as per the heading of this journal, I'm treating this as an experimental tank, not even close to a show tank. I'll purchase a nice tank when I think I'm at a level where I deserve to bring it justice so not yet. Hopefully this tank will bring me a long way towards that point.

I've only previously used organic soil capped with sand (so the classic dirted tank). That provides good growth for around 6 months or so but if a lot of the organics start rising up and leaching into the water column, its not such a great setup for high tech tanks. Ask how I know!

I've never used aqua soil. I would like to try one day but for now decided to skip that and go straight to inert. Encouraged purely by some of you on here that have been using BDBS. That is what I would like to have used but not readily available in Aus so I'm using pool filter sand for this rendition.

Apologies for the rambling, onto the details.

Started around 5th January, did the full changeover from the old setup

Tank size:

• 122 cm x 47 cm deep x 45 cm high (uhmm so in imperial 48" x 18.5" x 17.5")
• Litres/gallons - 258 litres / 68 Gallons

Filter

• Just what I have on hand and had been using in the tank (Aqua One Nautilus 1100) so around 290 G/H so of course in reality a lot less than that. Only filled mainly with sponges though, limited the bio media.
• I have a perfectly working FX5 sitting in the shed gathering dust but I think too powerful for this size tank. That connected to a Yugang reactor though and one inch lily pipes could be a good combo. Will have to think about that for the future.

Wave maker / power head
- Aqua One 8000 reef sim (apart from obviously to help circulation - was mainly put in here to help with the CO2 distribution - so is now situated at the opposite end of the tank to the filter outlet/inlet) Flow from 528 G/H to 2113 G/H. Have it on the lowest setting and probably still too strong

CO2

• Aqualabs Pro dual stage regulator (recently added this, replacing a cheap chinese one from ebay - about 6 times the cost!)
• Aqualabs inline diffuser
• Gets to around 45 ppm but I need to do some more refined testing ( I only have the JBL CO2 kit but seems to be working ok)
• CO2 starts 3.5 hours before lights start and 4 hours before lights build up to their set level.

Water
- Tap (GH 7 KH 6), PH is around 7.6-7.8 out of the tank - at the moment

Substrate
- Pool filter sand only

Lighting

• Week Aqua L1200 (using Red preset at R - 64%, G - 71% B - 44% and UV - 90%) TBH not sure the UV light does much but it is what it is.
• So the lights aren't on that high, I started off the tank even lower but crept it up to what it is now.

Initial plant list (as mentioned just selecting some from previous iteration of this tank)

• MC as the front carpet
• Hygrophila corymbosa (restricted this quite a bit as it grows too fast with direct CO2 access) so hidden in the opposite corner to CO2 lol

-Blyxa Japonica (one of my favourite plants. Its easy to grow but I wish it would grow maybe slightly slower so it doesn't start to take over it surrounds)

• One amazon sword - I wanted to keep one in here to prove you don't need rich substrate
• Crypt wendtii brown - similar to above
• Ludwigia repens
• Helanthium bolivianum 'Quadricostatus (I think thats what it is or similar. produces runners like nothing on earth but a nice looking plant. Thats the one in the back right corner in the first photo of the new setup)
• AR Mini
• Hydrocotyle tripartite mini
• Limnophila Aromatica

I've deliberately not used what i call starter plants to kick it off as I find they can take over easily in a high tech tank, then you have to gradually rip them all out. I know a higher risk of more algae without them but lets go!

Ferts

• DIY Macros and micro mix - Rexolin APN (dosed for water tank volume)
• Started 9/2/20 now 10/2.5/20 (yes I know quite low for an inert substrate compared to most and will gradually increase this in time)
• Front load around 50% Macros, then the rest dosed throughout the week - only just started this method to try and limit the swings during the week
• Micros dose evenly throughout the week adding up to 0.45 fe / week

Water change
- Currently around 55% weekly (I will be refining this a bit more too. I have a TDS meter now so will be working out exact water change volume using Rocco's TDS method which will also help with refining the fert dosing)

Current fish list

• Around maybe 15 Rummy nose
• 4 SAE's
• Couple of oto's
• 4 Corys
• 6 Crimson spotted Rainbows ( i received these in a swap, plants for rainbows )

I plan to gradually increase the rainbow collection a bit too over time. Love the Boseman's

Other miscellaneous stuff

• Fluval SK400 surface skimmer (seemed like a little toy when I first set it up but does an ok job actually)
• Aqualabs pro skim lily pipes, and added quick release to the filter hosing to get to these easily. They are glass.
• Inkbird wifi heater control

Upgrades planned

• RO/DI - Just received but need a few more bits and pieces then I'll introduce the RO water over a 4 week period (25/50/75/100). I plan to remineralise to around 5dGH (4:1 for CA:MG), wont be adding any dKH, again following you guys lead here. I think this will be a huge upgrade as my tap water is sourced from a creek and is inconsistent. PH varies between 7 and 8 and KH has risen from 4 to 6 over the last few months.
• CO2 reactor - Looking at the Yugang of course. This will also I think make a big difference compared to inline diffusers. When setting up the tank I put in some work to try and determine the best flow to maximise CO2 distribution but still think I haven't got it right.
• New tank - as mentioned above
• Possible auto fert doser for the next tank

Ferts uptake and adjusting over time:

• The NO3 seems to provide a consistent 10 ppm before each water change which is the same amount I'm dosing now. Coincidence or is it only using what's readily available in the system. I know with slower growing plants and not a huge plant mass the uptake is obviously less.
• PO4 - similar story, test (which I'm not sure how accurate it is) seems to provide a consistent result of 2 ppm, again similar to what I have been dosing.
• I'll gradually increase both and see where I can find the sweet spot but may wait mainly till after the RO/DI is running.

My initial aim is to try and avoid the infamous diatom stage by using a slightly reduced light schedule and ferts to start the tank.

First impressions for me is the driftwood is too large for this tank but it is a different piece so will persevere whilst in this tank.

Anyways the pic of the tank before I pulled it down;


Start of the new scape.

You can really see the crappy condition of the tank here with the scratches, water stains etc. I'm not too bothered though. It will make me more look forward when I eventually get a nice tank.

Just after filling up and initial planting. You can see the big heavy rock on the right. Without it, the driftwood shoots all over the place.

Noting that entire lot of MC melted soon after this, it wasn't in the best condition when it started though. Hoping it will eventually start up again. I'm patient, uhmm kind of!

Hi all
My Cambomba sometimes develops these roots from the nodes.
Rotala H'ra does it too, but not as aggressively as the Cambomba.
Any ideas why this happens?

This is the future home for the announcements when someone obtains an achievement badge. Let the games begin!

This journal documents my thought process and design decisions for building mini yugang reactors for tanks below 20 gallons/60P.



If this is your first time learning about a yugang reactor, head over to this article:



Yugang CO2 Reactor - A Guide



One of the challenges with the yugang reactor is that they are tough to build for smaller tanks due to material availability. But that issue was solved in this thread below:


Yugang Reactors for Smaller Tanks



After reading the thread above, I thought that the PC cooling reservoir would be a great idea for three reasons:

1. You will be able to disassemble it for cleanup
2. It’s see-through, so you can adjust flow as required, as the flow will decrease over time from filter clog-up. This is sort of important for mini yugangs as significant flow reductions could lead to a slower rate of pH drop. This is discussed in detail later in the journal.
3. Its outflow is off-centre and the cylinder is rotatable as shown in the photo below, thus you can increase or decrease pH drop based on your tank size. This feature is particularly important as the PC cooling reservoirs come in fixed sizes, so the only real way to adjust pH drop is by rotating the cylinder to increase or decrease CO2 absorption.

Challenges with the mini yugang and how to resolve them:

1. Low volume: I have used a 310 mm PC cooling reservoir, with a usable diameter of 40mm. This means that during operation at full capacity the volume of water in the reactor is pretty low; about 185ml. This is a little problematic as the low mass flow rate requirement of the mini yugang coupled with the low volume means that only a small amount of water gets injected with CO2 at any point in time. This leads to the pH drop being very slow for a tank size of 20 gallons. I had designed my yugang for a pH drop of 1.4 and it takes me about 5-6 hours to achieve this. The way to resolve this issue would be by using a reactor with a great length (to be able to afford larger mass flow rates) and a larger volume, but this would mean that you would have a tough time running the reactor in overflow mode as the CO2 gas pocket would have to be very small due to the bigger reactor size. The other solution is to start injecting early like I do. So to conclude, the “rate of pH drop” is dependent on reactor volume, mass flow rate and the size of the fish tank. So keep this in mind if you’re trying to use a mini yugang for tanks bigger than 20 gallons.
2. Usually small volumes of air being purged into the reactor isn’t an issue as yugang points out in his article but if the filter is purging out massive bubbles of air frequently then this most certainly will affect reactor operation. If you own one of the older biomasters one of the issues you’d encounter is the filter purging air into the reactor. This happens in two cases; if you don’t have a bypass or if the tee joint at the bypass is oriented incorrectly. This is why my suggestion would be to install a bypass, as it just gives you more control over the situation. So, what is then the correct tee joint orientation? If you look at the photo below, you’ll see how the bull head of the tee joint is pointing upwards against gravity and that the bypass is connected to the bull head while the reactor inflow is connected to the parallel down-flow. This is key because the bypass being connected to the upwards facing bull head ensures that any bubbles being purged from the filter is not entering the reactor; this happens as bubbles have an affinity to move upwards. In this case, the filter purges air and the bubbles shoot straight into the bypass and out into the tank without entering the reactor and disrupting reactor performance.

I hope the reader will find my experience helpful in designing their own mini yugang. Thank you for reading.
