I've decided I really like this tank and want to take my time with it.
I could really use some input, but this is what I am thinking right now.
I want to use Miracle Gro Organic topped with Black Diamond Blasting sand.
I have decided to build the overflow before I put this tank up and either build a 5 gallon sump or plumb it into a canister. Most likely I'll go the sump route for a few reasons, but primarily because I can use it as a a place for trimmings to grow out and sell or replant.
I'm leaning towards PaintBall Co2 on this setup, but not 100% sure. As it's 20x20x20 which is only 34 gallons before substrate I don't think anything more than paintball co2 should be needed. I already have some Paintball Co2 tanks floating around.
For lighting I'm considering 2x Finnex Planted Plus 24/7 20", but that may be too much so I figure I would start with a single. I can always add a second later.
I'm starting to look for a nice piece of driftwood, but might do stone. I'm not sure on the hardscape yet.
