Starting to plan out a future tank upgrade, going to likely move to an 48 inch long 80 gallon shallow reef, about the largest tank I can feasibly have in my house. I'm trying to plan out budget and I was thinking of using AI Blades, would the 39" with the elevated arms be the way to go? Was thinking starting with 2 grows and adding a glow a bit down the line. Or would it just make more sense to go with 3 Primes? (About 16 and a smudge inches deep tank). I like the light spread better on a blade but not sure if it makes sense over the primes. This would be moving the corals over from my E170, mostly LPS with a couple basic SPS (Birdsnest/Stylo/Encrusters). Just looking for feedback as I plan.
