Sorry Dabandit, I'm not planning on that much maintenance. I thought you you were thinking I had a smaller canister. I've seen O.C.D.'s tank and he has ran this type of set up for 8 years, His tank is crazy. He runs like 500lbs of life rock. But all he said in the canister was nitrate reducing media. I'm just wondering would live rock be better? or something else? I don't know his maintenance schedule. But really isn't the sump a place for equipment and the skimmer does all the work. So with enough live rock would the canister be better empty? Confused
