Lookig over your specs it looks like you have a ton of light. What is your photoperiod set at? Just recently I cut my photoperiod down from 10 hours a day to 4 hours on, 1 off, 4 hours on and it helped with the GDA I was getting on the glass. From the pics you posted I see the lights are hung a decent height above the tank but it still seems like a lot of light. FYI I have 216 watts fo t5h0 over a 75 gallon at 3" above the top of the tank.
Your water specs don't seem to be too bad. When I test my water I end up with 15-20pmm Nitrate and about 0.5ppm phosphate. I would try playing around with your lighting schedule.
