Ludwigia repens, hairgrass "eleocharis palustris" and ludwigia glandulosa all found locally growing emersed beside water and all growing submerged in water. Nice freebys if they survive the transition theres 20,000 stems in this tiny little pond. all clean no bugs put in tank with no fish to be safe will peroxide dip it before moving into other tank. 1 bunch l repens last pic I picked 8 days ago grown 2" and top turning more red with no melt at all. Well see how it goes. All found beside my local Lincoln dealer parking lot lol.
I've got local emersed plants before I know where theres a storm of lemon bacopa and anacharis is. Seems it always melted badly to mush. These plants are growing emersed for a week then submersed for days when water levels go up. Maybe they are more hardy being grown above and below water over and over? They may all melt to turds in weeks lol.

Got inspired by @Naturescapes_Rocco So I decided to do a full day of testing on my CO₂ levels yesterday for my UNS 60U before I add livestock, and I put together a graph. It was a pretty interesting test. My CO₂ comes on at 12 PM (3 hours before lights), lights run between 3–9 PM, and CO₂ shuts off at 8 PM. Injection during this test was 66 bubbles in 30 seconds, which equates to roughly (2.2 BPS)

I used an Apera PH60 for the pH curve and a Hanna HI3818 CO₂ titration kit to independently check CO₂ concentration

Current water parameters are GH 5 and KH 0

Hanna results:

12 PM (pre-injection): 8–10 ppm
3 PM (lights on): 41 ppm
8 PM: 49–51 ppm

pH went from 6.47 pre-injection → 5.61 by lights on, giving me a 0.86 pH drop by the start of the photoperiod. From there, it continued down into the ~5.5x range and plateaued through the rest of the photoperiod, putting the total drop at roughly 0.9–1.0 pH

Planned livestock is Cardinal Tetras, Pygmy cories, a few Amano shrimp, and eventually Caridina shrimp as the tank matures

What was interesting about this test was that as the photoperiod started, I was right where I wanted to be. It held a pretty steady curve, but later in the evening, just as the lights were about to go off, levels reached a little higher than I'd like. Ideally, I'd like to be somewhere around 40–45 ppm throughout the entire photoperiod, so I slightly adjusted my injection rate down to about 60 bubbles every 30 seconds, which equates to roughly (2 BPS)

I probably could've done just fine with livestock at my current rate, as I know guys like @Dennis Wong and Tom Barr run their tanks around ~50 ppm peak, but I know some shrimp, especially Caridina, can be sensitive to higher CO₂ levels. I'd rather be a little more conservative and play it safe. Plants are all doing very well

I'm going to do another full-day test at the new injection rate and see how the tank reacts. Hopefully I can balance the curve a little better and stay closer to that 40–45 ppm range throughout the entire photoperiod

I may also need to increase the CO₂ duration and start injection about 3½ hours before lights on instead of 3 hours. Ideally, I'd like CO₂ to already be around my target concentration when the lights come on rather than continuing to build afterward

Curious what those of you who run higher CO₂ with livestock think about this approach, especially those keeping shrimp. Has anyone else ever done a similar test?

See this post regarding AR Mini trimming/planting, and this post regarding Cyperus helferi trimming and planting!

I have hardly seen this subject talked about enough, but I think that it's one of the biggest reasons contributing to beginner's algae-filled downfalls! If you're buying plants from big stores like Aquarium Plants Factory (really good btw), Buceplant, etc. 90% of the plants you are receiving are terrestrially-grown.

Here's an important fact about terrestrially-grown aquarium plants

100% of all terrestrial leaves, when submerged under water, for any plant, will eventually get algae and die.
Some can take a while (anubias, java fern, cyperus helferi), while others will either melt (Crypts) or quickly get algae (AR Mini, Staurogyne repens, stem plants, etc)

But what about buying submerged-growth plants? From hobbyists, or BurrAqua, for example?

There is still a chance that your tank's conditions are different enough that many, if not most leaves you plant, will melt/die/attract algae.

How do we fix this? By leaving only enough leaves for the plant to continue to absorb light and put out new growth. Usually the top 4-6 leaves for stem plants.



It's a lot of work up front, but you will MAJORLY reduce the amount of waste, DOC 's, and algae-inducing scenarios if you trim your plants before planting.

I've done this in ALL of my tanks in the last 4 years with great success.

The easiest way to do this is with stainless squeeze scissors over your sink:

Here's the ones I recommend.

Yes, it takes a ton of patience. But if it could make a big difference in preventing the 2-3 month algae bloom in your tank, would you do it?

Here are some specific plant examples:​

For most true stem plants, I like to leave 3-4" of stem, trimming roots if necessary, and leaving only 4-6 of the freshest leaves. More than that, they will eventually be algae magnets. Less than that (like 2 leaves only) they might not survive the shock.


Lysimachia nummularia 'Aurea', only a few top leaves left, 3" of stem.


Hygrophila corymbosa. Note how I left the leaf nodes on the stem? That's where roots will grow from. Almost all stem plants need nodes to grow roots, even if you've removed the leaves from them.



Terrestrially-grown AR 'Mini' from APF. See how I did the same in this thread for my previous tanks.



This Anubias barteri var. coffeefolia was grown terrestrially (often called 'emersed' or emergent) in a greenhouse. I removed all but the newest 3 leaves, and trimmed the roots too. Terrestrial roots are quite different from submerged with certain plants.



Almost ALL Cryptocoryne species are grown terrestrially. These plants grow as a Rosette, where the inner-most leaves on the "stem" are the freshest, and the outer-most are the oldest. I removed a TON of old terrestrial leaves, leaving just enough for the plant to be able to grow new submerged leaves in my tank as quickly as possible, while leaving as few algae-attracting terrestrial leaves as possible. I also trimmed the roots, which were 5" long upon receiving the plant.



Lobelia cardinalis 'mini'

Penthorum sedoides. Would also look very similar for Staurogyne repens, too.


Did you know that Blyxa japonica is actually a stem plant? It looks like a rosette, but it's actually a squat, wide stem plant. The lowest/outermost leaves are the oldest, and even though this is a true aquatic plant with no terrestrial form in nature, I know that it likes to throw a fit and melt a good portion of it's oldest leaves when transitioning to my tank's conditions. Here's what it looked like when I received it from @Burr740:


Nice and trimmed up. Less problematic at the 1-2 month mark in the tank's development, I know it!

What about delicate/feather plants?
They're super annoying to prep. I still only keep the top 3-4" max.


With Myriophyllum mattogrossense 'Golden', I only keep a few inches and still try to remove some of the lower leaves that would otherwise just rot by being buried in my inert sand.



What about Myriophyllum sp. "Roraima"? F*ck that. Nightmare to trim lower leaves, just trim it to 3" (not pictured) and discard the bottom when planting.

Curious what you guys think! I know I could receive plenty of "I've never done this, my tank has been fine" but I'd recommend trying it first before having a strong opinion of it

By the way, all plants pictured were actually used in my upcoming 120cm Showcase tank:

As some people may know I had a long running journal on another forum. Glad to see Art get this new site started. A fresh beginning and loads of possibilities ahead. I'll be updating with thoughts here but for today just wanted to share my latest tank pics.

If you've been in the aquarium hobby for a while, I'm sure you've created or picked up so valuable hacks that fall into the tips, tricks and time-savers categories. So, in an effort to compile and share them, let's post them here.

This site is about sharing knowledge and experiences so don't be shy, no hack is too small or silly.

Please post yours.

I want to thank @Unexpected for introducing me to this new forum, but most importantly for him being the first ever to build the Horizontal CO2 Reactor. I feel honored that "Yugang Reactor" as he calls it (Yugang 鱼缸 means fish tank) is introduced in @Unexpected journal, but it would be a pity if that journal gets cluttered with too much reactor talk. So let me open a dedicated thread for discussions, questions and help on this Horizontal Reactor.

I have been experimenting for years with CO2, and at some time I took videos of my (modified) Aquamedic reactor to watch the bubbles in slow motion. To my surprise I found that the combined surface area of the bubbles was not very high for achieving a 1.5 pH drop in my 250 liter tank, and that CO2 absorbs so fast in water that the lifetime of bubbles is quite short. So .... we don't need to juggle bubbles at all, we can just create a very simple absorption interface between flowing water and a pocket of CO2 above it. The Horizontal reactor is surprisingly simple, and has some benefits that we won't find in diffusers or conventional Cerges / Griggs bubble reactors:

• Simple rules to find the correct dimensions for any tank, a small nano tank or a huge tank the size of a swimming pool.
• Very easy and cheap to build with plumbing materials. No fragile parts, low risk of leakage or malfunction.
• 100% CO2 absorption efficiency
• No need to experiment with vortices, venturis, diffusers, needles wheels, impellers / rotors, multi stage reactors - it is just a pipe with a gentle flow of water.
• No noise
• No mist in the tank
• No maintenance, and stable performance over time
• Virtually no reduction of flow from pump
• A purging valve is optional, as the reactor will purge itself from excessive trapped air.
• The reactor can be configured so that in the event of a failure, CO2 injection will not exceed a limit and fish cannot be gassed. Inherently safe.
• The reactor can be configured so that we do not need a precision regulator, because the reactor controls the CO2 injection rate

Or a multi stage version ...


A detailed thread can be found on UKAPS, linked with the kind permission from Scapecrunch forum moderators #1

I am happy to help new users to verify the calculations on reactor dimensions for their tank, please send me a PM.

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

Anybody else stay up late to watch the IAPLC rankings. As usual, my choices would have been different. Some scapes ranked in the 40s got picked by some judges as the best, so at least I'm not alone in that. Highest ranking by a U.S. contestant was Ryan Noel at, I believe, 31. Congrats to Ryan.

I am working on my mistakes…. The next one will be huge.

Instead of continuing the old build thread, I wanted to make a new one. This build might go just as terrible, but I want to put the old one behind me. I really wish I had given myself a month or two break because I feel like I have algae PTSD. I’m pretty burned out, and I sort of dread trying again. Oh well, too late now.

I wanted to try 2Hr Aquarist stuff, but already had the Controlsoil. I bought it a year prior (see previous journal) and decided to go ahead and use it. Hopefully I’ll make a successful transition to nutrient depleted aquasoil, and then restart with the 2Hr stuff later.

I didn't plan on starting a new journal until about a month in, but since my aquasoil is already starting to give out of ammonia, I need to get it going to get help making the transition to full NPK dosing.

With that said…..

Notes

• The Alternanthera reineckii ‘Mini’ was in bad shape when I opened the container. Might have been bad when I got it and then it was a week before I used it.
• 8-15-25: Added Synogonthas Vichada and Blood Vomit. Checked NO3 for the first time. It was 40. Started making twice weekly water changes.
• 8-18-25: Increased light to 45% of the full “Fish” setting. PAR should be just about 114
• 8-23-25: Pogostemon stellatus Dassen and Rotala Florida added
• 8-29-25: Discovered my NO3 was 0. Aquasoil is giving out way earlier than I expected
• Had a short diatom period, but it seems to be resolving
• I had planned to increase my light to 50% of full "Fish" setting which would be a (tested) PAR of 126, but right now, things are going so good, I don't want to mess it up. We'll hold off for now.
• 8-31-25: Starting to dose my own mixture of NPK and Mg. I really need to determine my actual water volume. What I am trying to dose, and what it tests as after I dose it are a good bit off.

Here you can see the older Rotala Sunset on the left. On the right is supposed to be Rotala Florida, but it is looking a lot like the Sunset did at the same stage. Argh!


Pogostemon stellatas Dassen changing from emersed to submersed form


Syn Vichada is doing pretty good. It is growing slow. The new growth is all green and the old growth is dying off. I want to cut old leaves and clean it up a little, but right now, I don't really want to disturb it. I watch it every minute. I loving having it.

Got on the tree build kick in past 2 weeks to make somthing I like for 36g freebie build to replace the huge tree turd #2 in there. I got 6 stumps ready today to get built for smaller tanks, 3 done today 3 waiting. Built the larger 17 tall 16 wide tree pics added other day to journal but gonna a build 2-3 more larger trees and the 6 smaller. Sell the ones off on eBay and etsy I don't want.
The larger stump 2nd post pic s 16" tall 15 wide plan to use in future scapes smaller. I've been using Amazon branch packs 15.00 for 25-35 pieces and amazon spiderwood 6-8" 5 for 12.00 for small trees. The large tree I made was a 10.99 piece I tore apart and used the 3 larger branches and built onto them to get the large tree in added pics cost me in end around 22.00 .... I have 10 pieces coming in mail Friday 5 large and 5 medium all spiderwood to make larger trees with this weekend.
Bought a ton of Amazon wood on Amazon lol 2 for 17.00 10-14" so I glued some of them together for larger usable pieces. some came out cool and well worth the 17.00 for the pieces glued together.The 1 has natural plant pots on top. The v shape last 2 pics 12" deep and 16" wide
After literally glueing a finger to a rock today Imao I quit! I ended up used all the accelerator I had anyway so Friday or sat before I can finish my smaller trees. will update as it goes, It will be a forest of trees when its done.
