I don't have it drawn yet, because it keeps changing....I look at the Megaflow sump filters, and the bio-chamber is above the water....I look at the CPR Aquatics filter and it appears to be mostly submerged....Then I see the SeaClear and they have optional air injection....I'm so confused
Basically I'm thinking something like the Megaflow... about 10" deep x 19 wide x 16 tall...stand pipe flowing into the first chamber....spraying over some sort of mechanical media, and dripping into the bio media in the second chamber... dripping into sump, which will house the heater and return pump.(I was looking at the RIO 1100)...I want enough bio filtering for 40gal min, and the most water I can get in the sump.
I guess the real question is how big do I need to make the Bio chamber???
