How to reduce shimmer on Kessil
I have a single Kessil 360WE over 32x24x20 (66g) tank. I had an extra one from my 210g tank which I am currently using it on this 66g. The tank is FO with no corals. I get this crazy shimmer which makes the tank look very dim. When I turn off my powerheads, I get no shimmer and tank looks great. Is there any way to reduce the shimmer? I tried to reduce the surface agitation by lowering the powerhead. However, I cannot eliminate the surface agitation. For flow, I am using eheim 1260 as return and 2 x vortech mp40wqd at 30%. I am not interested in par as I will not have any corals to grow. I just want the tank to look bright to maximize color of fishes.
thanks,
