my 500 gallon reef tank

[steve the plumb]

I took a par video of the reeftech lights outside the tank.The unit was placed 26 inches above the floor and I had a pad that was 24 inches x 24 inches.It hard to take a video when you are trying to take par readings.My readings are mostly at the floor level because it was impossible to hold the camera and tape measure at the same time while also trying to measure par.I will also try to take measurements in the tank but I will get my wife to help me with that http://www.youtube.com/watch?v=ryp9WMEJeuY

[steve the plumb]

I set it to public and saved changes yet it doesn't seem to work.I went and tried again and it says I changed setting yet its still private

works great for me Steve, so 118 Par for the reef tech and that is 2 " from the water line. That is if you had a bare bottom tank right. So people with 2-4 " would get better Par readings correct. Can ya give us a look at by using the par gauge and raising it up 1 " at a time to show us what numbers that you get.

Par at the bottom of the tank was between 125-138. I have hardly any sand in the tank.In fact because of my PH most of the front of the tank has no sand.I have around 60 pounds of sand in this tank.That's a joke for a 500 gal tank.Its like 2 buckets of salt.I had a good 300 pounds of sand in my 300 gallon.
