I am in process of setting up a 180 gallons tank. I have 2 MP40W. should I go with sand or no sand. I have sandbed (3" or so) in my 125 gallon with korolia 4 and i have sand storm if i want to have high flow. i want to cover the bottom of the tank just worry that the MP40 create sandstorm in my tank. I am thinking of 1" of sandbed this time but still debating of no sand at all for high flow. any suggest on sand bed? thank in advance
