Oliver, I've been searching for the answer to this and have not yet found it related to grow bed volumes.Originally Posted by Oliver
Based on the numbers you used above.
3.3gallons of grow bed
1 pound fish
3 gallon fish tank
Does the grow bed hold 3.3gallons of water with the Hydroton or is this 3.3gal capacity empty?
I'm planning out my system and want to ensure I have appropriate sized tank. I'm digging for an in ground tank with internal dimensions of 6'x15' at 3' depth. That comes out to 2,000 gallons for the tank which I calculate that I need 267 square feet of garden space at 12" depth and can handle about 660# fish.
Does that seem right?
I'm using the formula of 1cu.ft.=7.48gal.
