360_F_366160287_1O7OjMCIjv0XCpVAltN8y35N8w6MVbeN.webpI am happy to post the first Tin Foil Hat (meaning uncommon and unsubstantiated theory) thread.

Dosing a carbon source to an aquarium is a long-standing technique used in the reefing hobby to lower NO3 and PO4 through bacterial means. Vodka is a pure carbon source in addition to being a pretty good drink and is often used. Essentially, the theory is that bacterial populations in our aquariums are limited by the easy availability of organic carbon (not the type you are bubbling into it). By increasing the availability of organic carbon, you increase the bacterial population in your aquarium.

Bacteria are living organisms like our plants (and you and me). They respire and need a food source to grow. When they multiply and grow, they take up O2 by respiring and they take up NO3 (and to a lesser extent, PO4). This essentially competes with our fish and plants. We don't want that. Or, do we???

I did a podcast on this back in 2015 except I talked about dosing vinegar in your aquarium back then. It's the same thing as vodka but cheaper and not as much fun to drink. I'm proud to say our friend @Marcel G referenced my podcast in one of his posts.

What most people don't know (because I haven't told anyone) is that my thinking on this has evolved since 2015. I now follow a very focused method to my tin foil madness but please hear me out. Here's the story.

Ryan over on BRS TV was just starting to explore the hidden benefits of the aquarium microbiome in an effort to understand why new reef aquariums go through an ugly period when started. He was testing a dark start to avoid algae and allow bacteria to grow instead. People thought it was to cycle the tank but that wasn't the only point. The point was to give the microbiome time to grow and take up space. The theory was that if you allow bacterial to colonize the reef tank's rock surface, then it isn't as easy for algae to grow on it.

This got me thinking and so I put it to the test in a planted aquarium.

The theory was: Can I get bacteria to grow quickly in the initial phase of a planted tank so that algae would not be able to capitalize on the initial instability?

I've done three planted tanks since that time and in each one, I've dosed vodka daily for the first two months. I'm actually doing it now with my re-scaped tank.

The outcomes (and by no means scientific evidence): I've avoided the nasty startup algae that many people get. With the current tank, I'm even avoiding the usual fungus you get when you use spider wood in the beginning. Frankly, diatoms and dinos have also not been a problem.

All of this is observational and could be explained to be as a result of other reasons. However, after three times, hmmm... maybe there is something there. I do see my SAE's constantly nibbling on surfaces that I assume are covered with biofilm.

My completely unscientific guess is that the carbon dosing is causing bacteria to grow quicker than algae can. The colonize all available surfaces. By taking this space, algae has a tough time fixing itself to things, including plants. Bacteria can and will colonize the surface of plants and there are studies looking at the interaction of bacteria and leaf surface. I assume that the bacterial has also out-competed (is that a word?) the usual fungus I get on spider wood when submerged for the first time.

Now, some cautionary words:
  • The first time I did this I dosed too much and got a massive cyanobacteria outbreak
  • I have a well oxygenated tank, as bacteria will take oxygen away from the rest of the inhabitants
  • I dose a small amount (.8 ml per day per 25 gallons)
  • I stop dosing as soon as I feel the plants are growing well and can outcompete algae
So, now that you know about this, what do you say? Snake oil? "Art's lose his marbles?"

As the title suggests, I would appreciate recommendations from you experts for a good all-in-one fertilizer. My plan is to dose daily using a dosing pump (with additions after water changes.)

Preferences:
Can buy in larger quantities, 500 or more.
Can be purchased somewhere local or with free shipping
Reasonable price is always appreciated.

Links are appreciated. Thanks in advance.

Both tanks contain a lot of bucephalandra stems I have recently melted by feeding my caridina tanks with mulberry leaves. I have no idea what the heck happened but all buces melted in those tanks heavily over 3 days with every other plant + shrimp being fine. Don't wanna risk the plants dying so I'm throwing them back into high tech for a few months to recover.

Set Up:
Both tanks uses heavy co2 misting
Horticulture LED lights (dimmed, so probably 25-30 watts?)
Will steadily increase light weekly if I see no issues, max is 40 watts.
Dual sponge filters. (Air bubbles help prevent co2 gassing, also seems to really help stabilize tank, so less algae)
1 Internal filter with an atomizer for misting.

Regime:
All tanks get a 30-50% water change, twice per week.
Micros dosed daily (unless I forget, which happens fairly often.)
Macros Front Loaded and only in new incoming water.

6 Gallon bucket water change:
~350tds (Using seachem equilibrium remineralizer)
~22ppm KNO3, using KNO3 + KH2PO4
~40-50 ppm Potassium due to remineralizer
~4-5GH

Buce Lottery Colors
Lots of buces, various names, collected over the years. A lot of them were ultra rare and I cannot buy them anymore. Most of the ultra rare I probably accidentally killed from trying to grow them in a "no filter, no co2" style tank. Either way, not much color in low tech, will see what lottery colors we pull once they get going with better colors in higher lights + co2.

Both tanks are planted tightly front to back with bucephalandra. Kinda hard to see it all with moss blocking the way, but my view will be your view.

Random Mosses
Some mosses I've collected as well, honestly I grow a lot of them free floating so they kinda look the same. We will find out how they look after I attach them to something.

15 Gallon, very aged sand + pebble tank.
Image_20260415221525_401_1.webp
20 Gallon long, aged aquasoil I pulled from an existing caridina tank.
Image_20260415221528_402_1.webp

Wanted to take some macro shots, but does anyone know how to take an angle show on the glass without distortion? I have a DSLR long tube lens that works under water but color rendition is really bad.

Why so much moss?
Mostly to help stabilize the tank and to reduce light bleed. Less surface for algae to grow.

I started my first tank as an adult about a year ago, and have posted updates on it in my other journal , the Beginner Scaper Journal. I had intended the other journal to be a journey for this new tank but there were so many variables and many questions about the other set up that i thought it would best to start this new journal.

I am going to hold on to my beginner/amateur flair to the post since I think this is such a great hobby and want newcomers to know that everyone started as an amateur

Tank Inspiration
Dennis Wong's planted tanks. If you guys don't know who this is, I have already served a good purpose by introducing you to the founder of the 2Hr aquarist. He has a scientific horticulturist approach to planted tank that resonates well to my scientific mind. He is one of the few that I have read and listened to who mentions the different schools of thoughts when it comes to managing planted tanks and does not stick with a single approach.

Anyways a long winded rambling to say that everyone should read through the 2hr aquarist website. His products are all called APT (Advanced planted tank), and i think that is what his company was called before. His current display tanks are all planted tanks, which are beautiful mostly without hardscape but with lush plant growth and do not follow the rules of Dutch scaping. To anyone who wants to understand his philosophy more, i would recommend in addition to the website watch some videos where he has been interviewed.

I wanted to re-create this type of tank, but obviously as a beginner/amateur. I am hoping to learn more about growing plants with my ultimate goal to advance to a next scape which might be more nature style where i can take the knowledge from growing plants and now incorporate hardscape to it.

Equipment
Tank
- Waterbox mini 25
  • 60 cm x 40 cm x 40 cm
  • 90 liters or 24 gallons
  • This is a big upgrade from my 29 gallon standard tank. The silicone work is flawless.
  • It does come with a leveling mat.
  • It is deeper and slightly taller than a 60P or UNS 60U. I thought it would be useful to have more depth.
  • Background - Thanks to @Jeff Miotke suggestion
Stand
  • Waterbox stand - Black
  • The main contention is that it does not come with side holes like some of the other expensive stands do.
  • It just comes with opening in the back, so getting the tubing out is messy.
  • The door attachment is a soft close but it needs to be leveled which can be finicky
  • I did add a magnetic holder for tools and will add some light as well at some point.
  • It does come with leveling foot holders.
  • It is nicely built other wise.
  • I wish it came with a pull out like the Oase stands but guess would be very expensive.
  • Overall Ok, but nothing to highly recommend about.
Filter
  • Oase Biomaster 350 thermo
  • Replaced the biological media with Seachem Matrix
  • Replaced one of the foams with Seachem Matrix as well.
  • Steel lily pipes from GLA with extension. I think many of liked this company. But I personally would not buy anything again from them. They had quality control issues with this. One of the holders were metal and other acrylic and they would not send me another metal one. These are not the cheapest especially and you also have to buy extension separately. These are made by a chinese company and not made by GLA.
  • I used to have glass lily pipes but got tired of cleaning them.
Skimmer
  • I read many people commenting that using a skimmer attached to the inflow or outflow might be a pain to adjust, so ended up getting the Oase Crystal skim
CO2
  • Fzone Co2 inline diffuser
  • These work great and this is the second one that i have gotten. Trouble free but might need to replace parts of it if it gets clogged. Important thing is that it can be opened to clean.
  • I have a Fzone dual stage regulator
    • Cheapest that i could find and works very well - highly recommend
Water
  • I use RO water and remineralize it with APT Sky to a GH of around 4. Use the calculator on APT webpage.
  • My goals are to have a low KH, and GH of around 4 - 5.
Substrate
  • APT feast about 12 Liters
  • You can read about my experience cycling it here using Dark Start (sort of)
  • I did not want Aquasoil in the front of the tank and wanted a thin lining of gravel so used a gravel from Carribsea, and some smooth lava stones to separate them. More about this later but i don't really like the way it turned out.
Lighting
  • Chihiros WRGB II - 10th anniv edition - 60 cm.
Plant List (Links provided to their care on the 2 hr Aquarist website if interested)

Background
Midground
Foreground
Misc
  • Clump of Hydrocortyle Tripartita to absorb nitrogen - Trust me you do not want this plant for any other reason, will take over your tank and get everything into a tangled mess.

Fish List (Preliminary)
  • 4 Rasbora espei
  • 2 Otos
  • Will be adding more from my prior tank
Maintenance Parameters
  • Lighting - 30% - 8 am - 3 pm
  • Co2 - 40 ppm by Hanna co2 kit, 5 am - 3 pm
  • Fertilizer - APT 1 - Still not settled on a routine but the recommended dose for daily dosing would be about 2.3 ml and i do about 2-3 ml every 3 days.
  • Water changes 75% every 3 - 4 days, will make it weekly in the next couple of weeks

Photos
photo 1 - Day 11
Photo 2 - Day 20
Photo 3 - Day 21 - Current - Testing - Ammonia 0, Nitrate about 10 on API kit - Changed filter outlet location to get reduced current
Photo 4 - Day 21 - Side view

Thanks for reading so far!

There has been some good growth, some expected filamentous algae/diatmos and some melting, all expected hopefully this would not get too bad.
The Rotala blood red, Florida and Ludwigea arcuata are doing great. Both the florida and Arcuata seems to do much better on the aquasoil than on my prior intert substrate.
Blyxa melted a little but getting better, the Tulunadensis is struggling. The rest holding stable.
Interesting observation - The Rotala blood red, started putting out lot of roots and side shoots which i think is mainly because the plant was being pushed by the current to almost bend sideways and I believe it is thinking that it close the surface and doing its thing. With the changed filter outlet location I am hoping that it will be more erect and when i cut and replant there will be less roots. 2hr aquarist has written about this as well, but i think the bending sideways leading to rooting is not mentioned.

I am not liking the layout as much as i thought i would. Have been discussing with BurrAqua and have some suggestions but still thinking about this. Thoughts and suggestions welcome. Hopefully lot of people with (@Burr740 , @Dennis Wong @Art @techman81 @Pepere @Unexpected @Naturescapes_Rocco @Jeff Miotke @BenB @DutchMuch ) and without experience will follow and share this tank journey with me.

This is a great forum and i have tagged people that i am familiar with on the forum who have answered my questions and helped.

Hi All,

This is something I've been wanting to do for years, and I think I finally found a sensor that will work. I've always had trouble reading the API tests, and I've always been miffed that the reefers get the cool digital test readers - and wanted to take a crack at building one that could potentially read any freshwater test given a blank/known concentration as a calibration.

1781623047516.webp


A sensor came out from ams (AS7343) in 2022 that unfortunately has been made EOL, but has a replacement (TCS34488M) with a similar package that might work for future versions.
1781623191534.webp1781623224412.webp

I recently got my hands on a qwic version of the AS7343 sensor from sparkfun, and figured its time to put together something.

Goals:
  • As cheap as possible
  • Universal as possible
  • Fit API glass/plastic vials (not sure yet if the plastic vials will read ok)
  • Start with Nitrate/Phosphate and see if I can add more there

I figure I'll need 2 light sources (warm white, and IR for reading the phosphate test), but can use the same sensor array across most tests. I can use a small-form ESP32 as the MCU to give it USB-C power, wifi/bt connectivity if needed, and keep it small. Small/cheap ~1.3" OLED screen for displaying results/selecting tests.

Enclosure will be 3d printed.


1781624471200.webp1781624649923.webp1781624676599.webp
First pass at a sketch - I might drop the screen if I can give the device a web interface though, which will make the device even smaller/cheaper, reduces the need for physical buttons on the unit, and a 2nd pcb entirely. Also not sure if it will need a cover for the top of the vial, or how much ambient light will affect the reads. TBD. Will order some XIAO ESP32S3 to play with and see how far I can take it.

I'll log progress here, and am very open to suggestions and ideas. If successful, I'll release the files so it can be easily replicated.

Hello everyone!
I need a help to eliminate green fuzz algae.
My tank s 1250l + 250l sump. (250cm x 70cm x 70cm)
My filration is 10000l/h pump and 2x maxspect XF330. Inside sump KOI filter mats.
My weekly fers 15ppm NO3, 2ppm PO4, 8ppm K, 0.3ppm FE, 0.1ppm Mn I dose daily.
Last 2 months, weekly water change 50%, before that once in 2 weeks.
CO2 start 3 hours before lights go on.
My lights 4x chihiros universal wrgb 1200, 24x Daytime Matirx Sun Pro modules. Light runs around 65%. Par at substrate at average 90-100 umol
My problem is I had blooming of fuzz algae on all leaves, probably baceuse I had lean dosing, since I increased ferts, trimmed and replaced infected plants, it became better.
But still i see fuzz algae on a lot of leaves, I`1m feeling that I will need to restart tank from 0.
Will appreciate all your advises!
Thank you in advance.

I came into some Hygrophila polysperma "white" by Tropica recently. Grew it out and it seems to be able to be shaped into good midground bushes so I decided to create a layout to showcase it. Contemplated whether to use it as the only white plant in the tank, but decided to use some Anubias white petite as well so that the white polysperma doesn't stand out awkwardly.

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?

Time to start a new thread.

I’ll fill in some details later, but I’m working on the hardscape now. Any and all criticism is appreciated. The vision is nothing more, and nothing less, than something appealing to the eye.

90cm x 30cm x 30cm Lifegard Aquatics ultra clear bookshelf tank. Buce and anubias on the hardscape, stems towards the back and center, mid to front carpet with some changes in shade and texture down to a flat grade on the right side of the tank.

Lily pipe inlet and skimmer will be in the back left corner with the outflow in the front left to hopefully achieve circular flow. I’ll be running an in-line diffuser. Light will be the P600 Pro that I regrettably did not upside to 900. Oh well. I’ll mount it high and hopefully it’ll have enough spread.

I have some dragon stone and red lava rock rubble I’ll use at the base to blend into the substrate, as well as some stratum I may or may not cap with.

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?
