Hydor Koralia third generation wave pump 2450 gph

[Bikerharold]

Was told that 2 of these units would be great for my new 90 gal reef tank. Real new to this and would like an honest answer am I being over sold. Have people telling me more flow is best, others saying in my size tank these pumps will blow the corals off my rocks. Any suggestions would be greatly appreciated.:fish1:

I have 4 of them in my SPS dominated 120 and could maybe use a bit more flow. You'll be fine imo

Thanks for the advise. Will probably give them a try. Will set them up with the wave controller and see what happens.:fish1:
