Currently have a 3ft 65g tank but got a good deal on a 5ft 100g tank. I have 2 of the OG Prime HDs already so should I add 1 or 2 more, or consider a new lighting solution? I don't really have any issues with the primes other than I'm unsure of their output potential if I eventually go SPS heavy. Was considering going with a reefbreeders photon on the new tank. Thoughts?
