I have always liked Rotala florida as plant due to its strongly colored leaves, but realized that I haven't actually aquascaped much with it - meaning to integrate it as part of a layout and not just growing a bunch of it in farm/collector style tank. Using plants in a layout in tighter bunches, and in competition with surrounding plants/hardscape is much harder than growing it farm style in a single patch - it also means be able to shape/trim the bushes to match the overall curves of the layout.

Back in 2016 or so when I first received Rotala florida samples from north america, I could only grow it in sparser bunches. It looked nice in macro photographs but I could not envision using it an bush that would show off well as part of a layout unless I can grow it much denser. In the recent years, there were two main discoveries that I found in my experimentation, the first is that it grows better in moderate GH (5 dGH+) compared to super soft water (say <3dGH), and that it grew better in certain soil mixes (I experimented with different garden soil mixes when engineering the composition of APT Feast). Eventually I integrated some of the soil data into APT Feast's composition, and paired with the higher power lights readily available today, I find that I could finally grow the plant the way I envisioned as part of overall layout. I could prune it dense, as the base stems were healthy enough to sprout dense side shoots after trimming - and the secondary/tertiary shoot tips were as fully colored and sized similar to a primary shoot tip that hasn't been subjected to topping yet.

As a midground stem, it works very well due to its slower growth rate vs other colored stem plants.

Against the deep purple of Rotala florida, I found that Golden white clouds worked quite well. So now they are the main inhabitants of the tank.

Tank this week (25/6/2025)



Tank started out like this:

A week or 2 after initial planting (5/5/2025). I reused old aquasoil from the previous scape, so I planted all plants up front rather than waiting more time for the tank to stabilize, with the idea that I could out-grow any algae issues. Initially wanted to add H. Chai but it really didn't fit the overall color scheme, and the bushes by the side were too invasive to be compatible with having a chai patch I think.

Since it was going to contain Rotala florida, I thought I might as well throw in other high demand troublesome species such as the Red Eriocaulon quinguangulare, blood vomit. I settled on Rotala tulunadensis for the background as I wanted something dense and shapeable.

Tank specs:
60x36x36cm
Filter: Oase biomaster 250, all sponge media
CO2 injected through inline atomizer
Substrate: APT Feast
Water column: APT Sky to raise GH to 5dGH, 2ml of APTe per day.


Light distance. Interestingly, not crazy high PAR - just around 200-250 umols PAR at the substrate level.



Trimming and shaping: Most bushes were shaped by cutting individual outlier shoots one by one. Only Rotala blood red and the Rotala tulunadensis was straight trimmed across the entire top once.


This is how the Rotala tulunadensis looked like after a straight trim on 29/5/2025. About 3 weeks from when the top picture at top of this page was taken. It took the plant a whole week + to show new shoots. It seems straight trimming slows down the plant quite a bit, but allows for a very dense & neat canopy afterwards.



There are some interesting plants stuffed here and there. Some Eriocaulon caulescens? bolivia? that local hobbyists passed on to me. Carved out a patch for Syngonanthus vichada - slow grower, but the couple of babies that came have doubled in size so I think they should be alright. I think I will move them to a larger tank with more space.









Only discovered the color combination with the Golden white clouds when the tank matured, but its one of my favourite fish-plant combinations now. I think that while some of the species are a bit picky about growth conditions, one thing I really like about this tank is that most things have moderate/slow growth rates, which makes maintenance with regards to removing excess growth less tedious.
Elatine triandra is used as a low growing green filler plant - it does this role well. As it does not root very deeply, I can easily cut and pull off excess growth easily. Its the fasting growing plant in the layout that requires frequent removal of excess growth.

Some more close-ups.








I'm trying to replicate concepts of this layout (slowing growing bushes) into my 4ft tank.

Ive reorganized the order of my tanks so I can better keep track of them ie. Tank 2 moss tank is now tank 3. This helps in any confusion I had when tracking tanks they are in a sort of order now. Rather than taking time editing my old journal id rather create a new thread. Pics will be current (for the most part) as they are posted. I am not aquascaping. I am just farming.

I'm looking for recommendations for neocaridina retailers. I'd like to order them at the end of October, and have them shipped to Asheville NC.

Any recommendations?

Anyone familiar with these?

So I've somehow used up my gallon of metricide for excel, now I think you need a business license to purchase it on amazon.

I want to go back and try hydrogen peroxide again since its so easy and cheap to buy.

What ratios are you guys using to get rid of algae on plants such as BBA that are still somewhat safe for more delicate mosses?
Or should the mosses just be avoided for this?

1/2 peroxide + 1/2 water into a spray bottle for treating outside the tank?

Tank: Waterbox 20 AIO
Return pump: AI Axis 40
Lighting: (2) AI Blade Fresh 12”
Dosing pump: Ecotech Marine
CO2 injected

The purpose of this tank is to maintain a healthy planted tank for at least 1 year. There is a stipulation that I must be able to do this using my tap water for water changes.

This is my goldfish tank. I usually do a 50–60% water change once a month, but not because NO3, PO4, etc. become an issue.

Even after 4 weeks, NO3 is usually around 5–6 ppm and PO4 around 0.2–0.4 ppm.

The main reason I settled on doing water changes once a month was that, at around the 4-week mark, I would usually start seeing some brown diatom algae and green dust algae.

I dose ferts daily in this tank—macros in the morning and micros in the evening.

My weekly dosing is roughly:

• NO3: 8 ppm
• PO4: 2.8 ppm
• K: 40 ppm
• Fe: 0.17 ppm

Other water parameters are:

• Ca: 30 ppm
• Mg: 10 ppm
• pH: around 7.6–7.7
• KH: 3 dKH

This time, though, I couldn’t change the water at the 4-week mark, so I just let the tank run. It has now been 6 weeks without a water change, & I’ve had no algae whatsoever.

Now, I understand that water changes aren't just about NO3 and PO4. They also help dilute/remove DOCs, hormones and other things that may accumulate over time. but i think DOCs cause diatom algae hence the appearance of diatom would mean ( for me) water change

So I basically have two questions:

1. Is there any practical way to measure DOCs in aquarium water?
If there is, I’m thinking that might give me a better idea of when the tank actually needs a water change rather than just following a fixed schedule.

2. Could I realistically stretch my water changes to once every 2 months or so?
It’s only 4 goldfish, around 3–4 inches each, in roughly 300 L of water. Nutrients don’t seem to be building up, and the tank seems perfectly fine even after 6 weeks.

What do you guys reckon? Would you be comfortable running it for 2 months between water changes?

It’s time to take down the 20 gallon long tank that was my first “ high tech planted” aquarium and upgrade to a tank with on an appropriate size/depth.

I’ll order a Landen (90 x 50 x 50) tank on Amazon for this. Free overnight delivery. Preposterous!

I’ve studied the thread TRyan posted on 3/4” plywood stands and will be building a stand for this - thank you TRyan!

For filtration, I’ve been studying JayP’s thread. I had a biomaster thermo 350 on the 20L which I’m thinking of reusing. And I also have a netlea prefilter sitting around and an ARC small acrylic yugang reactor I can steal from a tank. I’m thinking of buying an Oase 800 or other pump and chaining these pieces together to provide a second filtration/carbonizing path? Not sure on the pump manufacturer & size?

I’ll be putting this together in the style of the ADA nature aquarium. Aquasoil in the back, some hardscape (rock, wood) in the midground and a decorative sand foreground. Very simple. Primarily a guppy, Endler, Cory, pleco, neocaridina tank.

Soliciting the scapecrunch community for feedback, advice, suggestions, etc.

Thank you as always. You all are the best!
