Ai Thirty Two HD

[ChristianAl]

I have 90 gallon (48" long x18" deep) tank.. I currently have Hybrid 4x T5's and I added 2x Thirty two hydra. My question is how many 32 Hydras do need to light up my tank?

Depends on why coral you are putting in, if you’re doing sps only then maybe a third or 4th one will help, but thats pretty good for a mixed reef or lps
