My in stand sump space is pretty limited so I had to squeeze alot in. I have a 20g sump with a diablo 200 skimmer a manifold that feeds my 2 reactors, one which is for gfo(not on right now) one feeds my carbon/zeolite reactor, one to the chiller(next to my tank), one to my calcium reactor(in my basement) and one I use to acclimate fish and coral ..
It's a mess under there. I only wish I could have it as clean and tidy as come guys here. But it is functional even though it looks like a mad scientist project. Lol
This is the inside of my DIY 2x4 stand for my 57 gallon rimless tank. I used French cleats to hold the front door in place...
Inside is a Trigger Systems Sapphire 26 sump, a Deltec SCA 1351 skimmer, a Turbo’s Aquatics L2 Rev 4 ATS, a Neptune DOS, a Sicce ADV 5.5 return pump, Spectrapure ATO pressure tube sensors and a couple of Innovative Marine Mighty Jet DC pumps to run the ATS and the chiller.
Here is a shot with the ATS endplate off so you can see it better.
My Apex controller is housed in a remote cabinet to protect it from moisture intrusion.
My stand houses a 75 gallon sump with a lot of cheato, algae scrubber, simmer, dosing pump, return pump, gravity fed auto top off tank, and 13 gallon QT system. Everything sits inside of a shower pan liner that has saved my floors several times.
Still on the work bench, the back will hold the electrical panel and i intend to keep this one open with an industrial/lab look. It's a frag/display tank for my office, the idea is to show the guts and make it pretty, lol
