TDB’s 320 Reef Par Measure
Thank You James for coming over and having a beer, ribs and helping me measure my par. My lighting consist of 12 LED fixtures. 4 120 Watt Apollo Dimmable 4 AquariumLED.com 120 LED and 4 24 Watt magenta/blue 48” stunner strips. The Aquarium LEDS are sitting on the glass near the back wall. The Apollo are mounted about 10” above the water in the center/front slightly angled toward the front corner and the 48” stunner strips and in the back1/3 and front 1/3. We tried to keep the data points as close as possible. The measurements were taken with the power heads off but the return pump on. We did two tests. The first is with Blues on at 100% and whites at 40% all of the rest of the LEDS on. The second test is with Blues on at 100% and whites at 100% with all of the rest of the Leds on. The tank is a 320 Gallon 96X27X30. Here are the results:
Blue 100% White 40% (Current Setup)
Blue 100% and White 100%
* The Apogee Meter significantly undervalues blue spectrum and the values could
be up to 40% or more.
