I have a 55 gallon tank, and I have 3 powerheads: Tunze 6060, Seio 820, Seio 620.

My acro tips are bleaching.

I currently have the Seio 620 on the left side ankled (about 45 degree angle) toward the front glass. I have the Seio 820 on the right side, angled (about 30 degee) torward the rear glass, and the Tunze also on the right ride, but it is angled (also 30 degree)toward the front glass. My return has a diffuser on it and is angled down toward the front.

All of my parems are good:
Calcium: 440
Alk: 10.2 / 3.36
Salt: 1.265
Phosphate: .008
Temp: 80
trates: <25 (working on this issue now!)

Can my steady high flow be causing my Acro tips to bleach? What would be a better placement plan for my heads? Is it too much flow?
