3 AI's or Radions?

He has a bunch of supplemental LED tho, no?

he's got 3 AIs and a couple strips to light the front and back.

i think he's covering more than 18" front to back.

im uploading a picture now of my 18 with 3 AI, give me a few min

Close ups of corals would be good too.

Ok, that coverage looks ok, and the corals look to have kept their color. How have you got those mounted, and how high?

12" above water level.

all 3 mounted onto an aluminum U channel rail.

still working on a vertical rail system to make them height adjustable.

Good, so it looks like I can get away with 3 then. Are these the white or blue?

blue

Perfect. Thx.
