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!

Questions? Ask below! I love to help out.​

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!

I have discovered that planting out aquascapes, especially when one doesn’t yet have a large enough ‘farm tank’, creates a bit of a hot dogs vs. buns problem. Order too many plants, now you need somewhere to put them.

Having recently planted two smaller tanks, I found myself, once again, with an excess of plants left over. I have four choices. Throw them out. Put them in my holding/quarantine tanks (that are already beyond capacity). Start a new tank (but I don’t want to move it later). Or try my hand at some little terrariums?

With the holidays coming up, I figured I would try the latter. I had the plants, and some extra jungle soil after making a friend a Shizuku for Christmas. I found some cute little terrariums with built-in LEDs on Amazon. At least this way I can use up the plants I have, and have decided I will gift these to my employees for the holidays. As they have the light integrated in the lid, which does have an adjustable vent, at least they won’t need to source their own light.



It was fun to play with some stones I haven't used in an aquascape. Jade Stone, Millenium Stone, Dragon Stone, and Dark Seiryu, and I knocked these four out over the weekend. Not complicated, but at least the plants now have a chance to do something other than wither away in their pots and TC cups. My Lindernia started blooming out of its holding tank this week, and I never realized what lovely little blue flowers they have when growing emersed. So a little of that found its way into the jar with the Millenium Stone. Hoping it makes it!

I am curious how many of you also dabble in growing some of our standard aquarium plants in emersed setups? I can totally see myself making more, maybe a Neo Glass Air next. Nobody warned me how much of a slippery slope this hobby was going to morph into when I started back up a year ago. Are there enough of us that would make it worthwhile to set up a ‘Planted Terrariums & Paludariums Discussion’ forum here to share our setups and experiences growing emersed? It’s still scaping, and growing plants, just with a little less water and maintenance. Or would that be outside the scope of this group?

With all the talk on Amazonia pro, I wanted to get some basic understanding of rich aquasoil.

- everyone seems to agree that the richer the aquasoil is, the more the amount of water changes you would have to do initially. Basically meaning that aquasoil leaches its contents into the water and you replace the water. Now….. doesn’t that just mean that you are throwing away what you paid for ? Even if one does a dark start, and minimize the number of water changes one still has to do a water change after the dark start and still end up wasting the nitrate/phosphate?

—— trying to ask then does that mean the only person who benefits from a super rich aquasoil is someone like an insta or YouTube person who wants a quick burst of growth with the initial leaching of nutrition. For everyone else wanting a stable long term system, a not so rich aquasoil which might help the plants a little bit in the beginning but being used more for long term stability and buffering capacity?

- do the plants actually get the boost initially from the root zone or is it more from the leaching that happens and ultimately from the WC? The later makes sense since their roots have not yet developed.

- if one has the whole substrate inside a container with water, wouldn’t water touch all aspects of the substrate regardless of it being capped or not ? How does capping a aquasoil actually help? Green aqua stated that ada recommends capping the Amazonia pro with Amazonia 2.

Curious on people’s thoughts on this.

My new scape. It’s been a while. I’ve been busy finishing my novel. It’s published now so back to scaping.

It’s a classic triangular scape and I’m calling it Quantum Entanglement. It’s a working title, so I might change that. Sorry mods.

The real star is the light. Off Amazon for around $130. Fully controllable with a remote. Great value. https://amzn.eu/d/0eRX5eCo

I want to plant it with mainly buces and small anubias spp. on the rocks and wood and MC carpet, with some crypt nevellii or C. X Willisii, and stauro in the shady parts and maybe a ludwigia mini super red highlight behind the last rock on the left.

Hey all,

Just wondering what your thoughts or experiences are with running some form of moon or dusk lighting.
With my tank only running 8hrs of light per day, I have recently added a 2-3% setting on my Chihiros WRGB II from 18:00 - 21:00.
It's running quite a blue light and is just so that I can still get some enjoyment from my fish when I am at home in the evening.

Does anyone else do this in planted tanks? Do you think it will create algae issues?

Cheers

His study answers many questions and is filled with data for folks to pour over.

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

Well, as this thread exists in a few places, I figured why not have it here also. Perhaps we can take up the baton and keep it active and bring some value to hobbyists.

For those of you that don't know, I got into thinking much more about my micros when I read this thread on another forum. It was started by our very own @GreggZ. It was spurred into existence because of our own @Burr740 and his work with micro fertilizers. Some really good discussion followed and a lot was learned.

I don't want to steal Gregg's thunder with this so I hope he posts his current thoughts on the subject and we can all take it from there.

All the best,

Art

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.
