I’m going to take a new approach to this. What would be the best filtration for a 29gal reef tank. 2in of live sand plus about 40-60 lbs of live rock. I want some nice fish and corals once it’s ready. I was under the assumption that a sump would be best but a few people have said it’s not worth it in a small tank. I will have RO auto top off no matter what filter style I do. I have a spare marinland 150 & 250. Would either or both of those work together (chemi pure media) or are their other filters you guys recommend?
