Radion xr30 gen 3 on a jbj 20 gallon frag tank

[Legonch]

Ive got a xr30 on a jbj 20 gallon frag tank. Im using the rms mount system. Question is, what percentage should I start with? Im new to radions. The water isn't that deep obviously. Frag tank has sps and some zoas, and lps.

Thanks

Thats a powerful light on a small footprint. I don't run LED but I would guess you need to set it to 'bugger all'.

bugger all, haha! Im only running it at 25 percent......

anyone else have any ideas?
