I am new to the hobby and tried to do a lot of research to avoid mistakes. I know I will make mistakes, but I want to keep them to a minimum. Currently I am setting up a Red Sea Reefer Nano ( 21 gallons in the tank and 7 gallons in the sump). The manufacture suggests a pump that can return 530gph. I have read that SPS corals like high flows, LPS medium flows, and softies low flow. If the pump is returning 530gph , is that considered high flow, medium flow, or low flows gieven the size of the system?
