Getting back in the hobby with my 72”x30”x24”t 225 gallon. I am going to have sand(2-3”deep), minimal live rock, and mixed reef(“easy”sps). It has a center, internal overflow. I’d like as much flow as possible without sand storms. Any recommendations?
There are a host of options; Tunze Turbelle and Ecotech Marine (in different sizes) are among powerheads that I would buy. Some people build a closed-loop system (external pumps recirculating water), but I would always go for powerheads for flexibility and the sheer variety now available. I would not worry too much about sandstorms; they are inevitable at first, and with careful placement, you can avoid kicking up the sand and still have great random flow.
