How close to the glass was the meter? We found that the light reflects off of the glass and hence the center of the tank lower down actually had a lower reading when we tested a while back.

Same settings and both tanks have had the lights on for over an hour and a half.

Surface readings




8 inches down readings





16 inches down readings





Now the whole point to me doing this test was not to compare which was better but everyone knows that a good 250watt MH set up will be able to grow SPS easily. Now this shows that a good T5 set up does compare to it with close numbers. Sadly i wish t5's had the shimmer
