That's a fantastic idea! I think I may just do that.

Could always look into a simple plastic trashcan or Rubbermaid tote.

I had Marc from Melev's Reef build a custom acrylic ATO container. It's 14.75" long, 4.5" wide, 24" tall - approximately 7 gallons. This allowed me to put it on the right hand side next to the sump and use up some previously unusable space. The tank evaporates about 3 gallons/day max so it only holds 2 days worth of water. I put an electric solenoid on the RO/DI feed line and hooked that up to a programmable light timer that has it turn on for 1 hour M, W, F, Sa. Ta-da! Infinite ATO. I just check the TDS every once in a while when I hear it running, or when I make a lot of water for a water change and call it good.

Nice. That's always the worst part... The trickle of equipment just builds the excitement but you can't play yet...

Nice.

I used flex-pvc and it works just fine. I found it can be a bit of a pain just because it wants to curl, so running long straight sections is probably easier with regular PVC, but otherwise it worked great for me. As jolt mentioned, FlexPVC has some black sch. 40 PVC. I also had to get a few pieces on Amazon. What type of drain are you using?

I've got 2 gyre 150s and they are perfect for an 8' tank. Yes they do not have random settings but it's fine. And if you get an Apex you can set it up to control them and make it fairly random. I put in a 9.5" exhaust fan in our canopy that exhausts the air outside the house. It was a low rpm fan so it's very quiet and moves more than enough air to keep the humidity down. I also put it on a humidity controller so anytime the canopy his 60% humidity it kicks on. Considering our tanks have the same dimensions your more than welcome to swing by and get some ideas.

That's really cool to see the progress. It's looking very nice!
