I'm dealing with an algae issue as well. I've cut my lights back to 6hours blue and 4 hours white. I added 3 snails and an emerald. I also reduced feeding and increased my flow. It seems to be working, that means it doesn't seem to be getting worse, hopefully I'm on the downside of this issue. I've chekced my water and it seems to be ok but from what I've read the algae can be consuming the additional phosphates and nitrates. I'll be doing testing and pwc tomorrow. Personally I think you're running your lights way to long, but I'm no expert. I can tell you that many people are running a total of 9 hours 9 blue and 7 white.
