i dont have a sump my tank has about 150lbs of LR with a 3" fine crushed coral substrate. the tank is bottom drilled and water is sucked to my two fluval 404's that i run a high grade carbon (chemi-pure) and then returned through the top... i have 2 other power heads and a skimmer... i also have a uv filter
im not sure what it is my tank has been up and running for a good 2 years now and the water is very stable.... i can have a large snail die in the tank and nothing changes....
