I have a 25 gallon cube with a 15g sump, I have a pump that is pumping around 320 GPH. Is this too much flow for my clown pair? They are wondering around the tank, but never stop moving. I also have a cleaner shrimp, Will this be a problem for him? I’m new to saltwater, I’ve only had freshwater which tend to have a low flow. My clowns were in a 8g cube with a 20g aquaclear filter.
