I just tested my tank with BAR's PAR meter and bit concerned with the readings. The Kessil A350W is sitting on a 40B (36x18x16) 8.5" above water level & sand is 22" from the light... The 3 readings below are: Kessil Blue-100% + White-50% Kessil Blue-100% + White-100% Kessil Blue-100% + White-100% + Dual T5 Its top view readings (overflow back-center) & the #s in the center point of the tank is on the rock elevation 13" below light. Now to the readings... I see many others with 300+ reading on 350Ws, why is mine soooo low? Is it a wrong setting with the PAR meter? Or is this normal? Any recommendations? Here's the rockscape for reference.
