I alreay have one large reef tank that has a skimmer/sump/fuge setup and the only problem I have is with power outages. We have at least 2 a month and if its more than 6 hrs my overflow will let enuff water pass to get on the floor. My new fish only tank is a reef ready tank but I want to just plumb that into a large canister filter and now the tank becomes much less stress because of the closed system. If it does not work I am going to go with something else. I just want to make this tank 100% safe for my house and 100% worry free. I alreay have the canister so I am not about to ditch the idea. So if I go with a sponge, biomax , carbon combo. What goes on top, middle and bottom. I was thinking sponge on top, biomax in the middle and lots of carbon in the bottom. How does this sound?
