I'm getting ready to purchase 2 md40rxt pumps for my 90 gallon . Pumps are rated at 1360gph.They are circulation pumps not pressure pumps.I will be using one for return pump the other for a etss reef devil skimmer deluxe.I use a overflow box system rated at 600 gph
Would this be to much flow for the return?
Would I need to buy A Higher rated Overflow Box?
Would this be to much for the skimmer , they recommand a 700-900 gph
any insight would be appreciated...
