I have a 75 gallon tank and I just added 70 pounds of live rock this week. I am running a fluval 304 canister filter, mainly for water flow. I have two profile 601 powerheads. They should go at opposite ends of the tank, correct? They can be set to mix air in with the water as it shoots out. Should I be adding air?
