This weekend someone gave me 100 gallon tank and stand. I also bought about 65 pounds of beautiful live rock. Here's my question, if I use that live rock, some live sand, and a decent hob protein skimmer, what filtration can I get away with? I thought about 100 gallon canister or two bio wheel 350s, each does 75 gallon. I know where I can get an affordable sump but terrified of drilling. Any advice on running 100 much appreciated.
