Hubble's reef

Found the problem on the light, It was a loose connection.

Bought a par meter and got to checking numbers. These three Neptune Sky's put out a blanket of very even light. I'm sticking with the 40% and even with that it might be to bright on the sand bed for some low light LPS. I also started dosing bacto-balance but it bottomed out my nitrates and phosphates so I stopped for now.
