I have a 55 gallon reef right now, and I'm thinking about up grading to a larger tank. I'm thinking something around 100 gallons. I am wondering if there is anything I may be able to reuse from my current system. Right now i have one AI Hydra 52, a 20 gallon sump, protien skimmer (not sure what it is or what size), a 1/10 hp chiller.
