Sufficient powerheads?

I have a 90 gallon display tank that is 48" long. Will two powerheads rated at 1400-1500gph be sufficient. Tank will start as a Fowlr but eventually will keep Softies and LPS's (long way down the road lol). Thanks!

IMO, it's not about gph, it's about the flow for the entire tank. I always use four powerbeads to get good flow to the entire tank.

Should be good to go. Assure corals are waving in current and not bent over skeleton or bases waving vigorously. Base your flow needs on coral behavior and not the rating of flow per hour
