I have two hydra 64s on my 90. It’s a reef starting out. What settings should I use to help with algae growth on the glass? I have to clean the front glass in the morning and at night. It doesn’t cover it completely but enough to be annoying.

It’s ever since I got the second light. But it’s still there. I’m wondering if the lights are causing it. The tank parameters are fine.You should invest in a good nitrate/phosphate test kit like Nyos, Red sea or Salifert and check your water parameters first (you may be overfeeding). Second, dial back the red light on your Hydras to zero for the time being. Third, make sure your tank isn't being exposed to direct sunlight for a large portion of the day.
Those should all help, but without knowing your water parameters it's hard to speculate further why you might be seeing a lot of buildup on the glass.
