Ecoray vs AI Prime

[franklin2244]

I'm setting up a 75g. Going to mostly keep LPS and a couple monties. I have a Ecoray 112D(none dimmable) and one AI prime. My question is would I be better off with three AI Primes or two primes and my 112D? I'd use the primes as sunrise and set, while using the Ecoray at peak for the power house.

Looks like you'll need two Primes if you keep the current LED fixture. Link below for those unfamiliar with the Ecorayled.

Three Primes or two AI Hydras if not.
