90 Gallon AI SOL - Page 2

I have one over my 24x24 cube and it's great. That's half the dimension of ur 90, so two would work, three I think would be drastic overkill. I have the 70 degree optics btw

How do you get the 70 degree optics. Is that what they come with on a site like aquacave??? or do I have to call and order that specifically and if so would that cost more??

I have two AI fixtures on my 90 with standard optics and coverage is fine as noted in photo.

i have 2 AI on my 90g also and has been running 1+ years and has been supporting some good growth on my SPS dominant tank and has grown some nice colonies.

Wow, I guess 2 is enough for a 90. How far above the water line rlman? What is your peak intensity? Does any of your frags bleach near the top?

Mine are 8" AWL. Using sun up/sun down feature of AI but peak intensity is 75 for white, 90 for blue and 85 for r. Blue. And using 70* optics for the fixtures. Running peak intensity for 8 hrs/day.

Thanks, rlman. I have stock optics, considering getting all 70 degree optics. Only running peak intensity for 2 hours, maybe I'll up it a bit.
