Ai prime question

[Sexytang]

I have a 75g tank with 2 ai prime 16hd lfs said 2 would be plenty how high should I have the lights hanging atm I have them 14” with this setting

I would think about cracking those settings way up. I have 2 prime HD’s over a 40 breeder and this is what I use.

Yeah looks like your settings are too low but if you do crank up do slowly so you don’t kill any corals. I currently run 3 primes on a 40 and this is my setting

What r u keeping in the tank? I have 3 in my 30G + 2 more led strips to get par high enough for my acros. I keep them 12 inches above water.

I think it was 9 or 10 inches that BRS found the best par amd blending with the least amount of light spill
