I'll be using a barracuda on a 50 gallon
But it's also got to pump water up about 7 feet into two separate frag systems as well as through the wall to the display tank where it will be split in two. NOOOOOOO powerheads going in this beast.
I've got 89X the turnover in my 90 gallon which is a mixed reef. The 50 gallon will be all higher end SPS and a pimped out system
