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

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.

Inspired by the thread on CO2 controllers, and @Art experiment with modified pH probe / drop checker, I came up with what is to the best of my knowledge a new approach for our hobby.

I am not strong on the chemistry of CO2 in water, so it would be great if others chime in and comment if this approach makes sense.

Use the principle of Henry's law and fill the space under a closed aquarium lid with the correct concentration of CO2, using an affordable 65 USD sensor or similar with solenoid to release CO2 above the water. Control CO2 partial pressure so that the tank water will reach equilibrium with this gas pocket at about 30 ppm in the water. This would allow for very stable CO2 in the tank, and a big saver in CO2 as we don't rely on the outgassing via surface agitation to achieve stability. Besides that, it will be only weakly dependent on water chemistry (this may need to be tested and/or confirmed/quantified by chemists, as the chemistry and temperature do have some influence on CO2 solubility?).





Notes:

• My first thoughts/estimations are that one can reach 30 ppm in the tank water very fast, and have probably more than 90% savings on CO2 consumption. As we now measure CO2 in the gas pocket, independent of water chemistry, it would (hopefully) also be the first time that we can forget water chemistry as a major factor, complications with pH probes and using pH as a proxy, and indeed know the real water CO2 ppm more accurately and with less risks of misinterpretations of measurements.
• We don't need a precision expensive CO2 regulator anymore, no diffuser or reactor, no pH probe or drop checker. Just a sensor with electronics that switches a solenoid on and off. It would probably be good to have a simple air pump added, so that O2 and other gasses can exchange, but this would give very low CO2 losses.

From a physics and chemical perspective the approach is very similar (in reverse) to what professional dissolved CO2 probes do (see attached: measure CO2 concentration in a gas pocket that is in equilibrium with water), so that gives me some confidence that the above will work. However I am not confident that my understanding of chemistry of CO2 in water is good enough, and I may miss important aspects. Hope others chime in, and help to quantify if the chemistry is a minor or perhaps a major complication.

Attached file: Datasheet explaining the principle and use of a dedicated dissolved CO2 meter (for most in the hobby too expensive, but similar scientific principles applied as in above ideas).

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

This is not a step by step tutorial, more for inspiration and general information!

My very first DIY stand was a 100cm two-door home-depot plywood stand. It looks fine in pictures, but was NOT up to the insanely high, unhealthy standards of excellence that I hold myself to with everything:



No journal for this old tank.

The lesson here was: don’t use home depot plywood! It sucks. Find a real plywood dealer and spend the extra $.

My next stand was way more ambitious: a 150cm x 60cm stand, designed to hold up 2400+ lbs, made from quality baltic birch plywood. 3 doors, two interior weight-bearing vertical panels, adjustable leveling feet. It worked great, and can be seen in my two journals Many Lessons and Inert Sand Trials:


I did a WAY better job on this stand, and it now resides with @Kwyet ! Also, a spray finish really makes a big difference.

After that, the 90cm Experiment Tank stand. Two doors, and instead of a cumbersome middle panel, I used one hefty plywood column:


Scottish accent Fookin' crispay



This tank also had a waterproof, sealed bottom “rim” so up to 2cm of water would have to fill the stand bottom before it overflows. Useful for emergencies or leaks, when combined with loud water leak alarms! This stand and tank is in my garage, soon to be sold to anyone in Colorado who wants it!

The new 120cm stand:​

This stand is for my new 120cm tank! This stand is the culmination of seven years of stand-making. All of my mistakes, lessons, preferences, and skills were combined to make the stand of my dreams!

And of course, I had to move homes and got seriously injured, requiring surgery, while I was trying to finish it. Sorry for the lack of pictures!

I would not say this design is beginner friendly. It’s not expert, but likely intermediate difficulty. I have a Wen track saw and a Sawstop PCS Cabinet saw, which changes the entire process compared to someone working with more difficult tools. I also have a Graco Magnum X7 paint sprayer for a professional paint finish.

First, I started with mocking up the stand in Shapr3D, my modeling program:


My local lumber company had really good deals on 5x5’ sheets of ¾” baltic birch plywood.

IT IS CRITICAL for precision woodworking like this (no trim to cover up mistakes) to get exact measurements, particularly for the thickness of the plywood. For example, using a pair of digital calipers, this 3/4" plywood was 17.8mm thick (0.7 in a lot smaller than .75"), which is what I used in my modeling program to create the exact length of cuts to properly span 120cm long and 60cm deep.

I collected the exact measurements of each part needed, and threw it into Opticutter to determine how to best cut my 5x5’ plywood sheets:


You don't need to study these sheets; the photos are just to show you how Opticutter works to save you from creating too much waste, and using the fewest cuts!

Steps I followed for this stand:​

1. Cut all panels using table/track saw.
2. Make 4-ply support column. Make notch cut ~145mm from top of column to fit behind front brace. Glue and trim/clean.
3. Cut out "access holes" in panels, including pocket holes for front and back brace, predrilled holes for front brace (in middle, and upper portion for future front panel) and predrilled holes for back panel. Use a router with roundover bit to create round, smooth holes for cord and tubing access, as well as handles for moving the stand around!
4. Run the "standing height "of the side and back panels (and 4-ply center column) through table saw to make uniform height for all 4 parts. All of these 4 parts should be cut to the exactly same height.
5. Trim door “finger-pull” with a router. Just a 45-degree "slice" off the door's corner to make a finger pull.
6. To assemble: Flip top upside down, test fit sides and back, secure with screws. Make front edge flush, back can be trimmed down with router flush bit if necessary.
7. Attach the bottom panel, Make front edge flush, as the back can be trimmed down.
8. Add 4-ply column, ensure front edge flush.
9. Add front and back "braces".
10. Add front panel, and bottom "lips" that hold any spilled water in.
11. Spray and sand stand, fill gaps with Bondo wood filler. Sand and repeat until corners, cracks and divots are smooth.
12. Caulk the inner corners where water would be.
13. Paint stand and doors.
14. Attach doors.
15. Add feet.
16. Run electrical and LED strips.
17. Cut foam mat to size.

Here's some of the steps in the modeling program:


4-plywood-thick center column, with "notch" for the front brace to fit flush:


Top down first on a flat, even surface, then add sides and back:



Flip right-side-up, and add the bottom panel:



Add the rear brace, the front brace, and the center column. Make sure the front brace and column are flush with the front of the top/back panel edges.


Add the front panel and bottom lip pieces:


For the doors, create a notched finger pull (side view):


Door hinge stuff:

• Blum Clip top Blumotion Full Overlay, 110° euro style hinges
• Kreg hinge jig

And it's done! Here's some of the few pictures I DID take of this process, sorry! I had a lot going on:

Gluing the 4-ply-thick center column:


To make the access holes in the back and side panels, I 3D printed some plastic guides for my router bit to follow, then roughly cut the inside out so the router had less material to work through:


Perfect routered holes:



I learned to score the plywood with my box cutter first, so when it chipped from the rough jigsaw cut, it chipped ONLY to the scored lines:



I removed the excess interior material with the jigsaw, then routered. I also used a roundover bit (in process on the left hole, right hole not rounded):

Any chips or imperfections could be fixed later with bondo wood filler and sanding.


Once I had my access holes cut out, I could assemble! I used clamps to hold the panels together and flush, used an Incra T-Rule (amazing device) to mark a line that was the middle of my plywood panel's core:



Then, I drilled countersink holes with this bit for the screw heads to sit below the level of the wood:



Screws:
Since the screws on the top, bottom, and rear of the stand would never be visible, I decided to skip the annoying "pocket screw and glue" scenario and just go with crazy robust torx-head 1.5” construction screws. I LOVED it. Definitely my preferred method, though they really do require pre-drilling AND drilling countersink heads. Still, way stronger than pocket screws my god.

• SPAX #8, 1-1/2" Interior Flat Head Torx Wood Screws
• INCRA T-Ruler 6 inch for marking my ~8.9mm line (middle of the plywood core I was screwing into).

Wood filling and Priming:
Bondo wood filler is amazing stuff. I used TONS of it, this was just the first pass:

Apply, sand, apply more, sand more.


Then I primed with Sherwin Williams Gallery Series primer, and sprayed with a TrueAirless 515 tip in my Magnum X7:


Once the primer was dry, I sanded it, and sprayed again. Once dry, sanded again. Lots of sanding:



I wiped the tank down with tack cloth, then went for the finishing coat using a Graco FFLP 310 Tip and Sherwin-Williams Gallery Series Waterborne Topcoat in true black. Probably a matte or satin sheen, I can’t recall. Not cheap, good paint! Make sure to filter your paint through a find mesh before spraying.



By far the best, most perfect finish I've ever had on a stand. BTW, the doors are fully adjustable up, down, left and right to get them nicely aligned. Blum hinges rock!



Once it was all put together, I got some help to move it into the new house. And installed the oversized Aquarium Mat.

I paid Tommy, the owner of Aqua Rocks Colorado, a delivery fee to have my custom 120x60x50cm tank delivered and installed on the stand. Once positioned evenly around all sides, I trimmed the aquarium mat with an Xacto knife, and was finished!

I'm tired today, but I'll upload more pics of this stand soon to this thread and to the 120cm Journal, too!

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

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!
