Hey Everyone,

Long story short my cousin is upgrading his 65 gallon tank to a 110 and is giving me the 65 gallon tank reef ready. It comes with a 20 gallon long tank with baffles he used as a sump. With the dollar per gallon sale Im thinking of upgrading the sump to a 29 gallon or perhaps change it to a 20 high to make room for a quarantine tank. In the sump I will most likely just have a filter sock, moving bed filter and return pump. What is your opinion?

Also if I do upgrade sump how do you know how high to put baffles in order to make sure if the power goes out water won't overflow? Thanks!!
