Thought you might be interested in my par readings I took today. I am using 2 Hydra 26HD's , they are ii inches above the water and do have baffles round them. I have posted the profile details below and I took the readings between 3:15pm and 3:45pm. I used the Neptune PMK on the end of a pole! I do want to take some 24 hour readings in the same places in the tank at some point. Let me know what you think or if you have any advice! The two 322 reading were directly below the lights at a depth of about 4 inches. The tank has a depth of 22"
