so how about my lawn mower? is he gonna have to go too? my tank already has some yellow polyps and mushrooms and others and it seems like they are all doing fine iwht just 300 watts. im going to get my 1030 watt MH soon and see what i can do. I am thinking about taking out all my live rock, corals, inverts, and fish, and replaceing my C/C with a DSB. So where should i put the LR, fish, inverts and all the others. The LFS says to take out 60 gallons, take out all the inverts, fish, and lr, and just scupe out all of the C/C and then im going to buy 400 pounds of LS from him. Do u thikn that will work out fine? because i want to have all my fish in the tank at the end of the day after we are done replacing with live sand. Do you think this will work..? My yellow tang and my purple tang have ich right now.... man.. this is the 3rd time.
