I don't know much about the AI primes. The first thing that stands out to me is the cooling fan. It is an additional mechanical source of noise and potential failure. The Tuna Blue cools by design of the shape with no moving parts. The AI PAR looks to be maybe double of the Tuna Blue, so I think it would be enough for SPS if the coral was at the top of the tank.Thanks, that adds up to about the cost of the AI prime, so is an AI prime worth it? Will it be powerful enough for sps? What about a used one?
I have never used the AI Prime, make sure you get the "Reef" model.
