This, plus I don't know your tank, but you could use carbon and/or purigen or other waste removal products in your filter, before they breakdown. What kind of plants do you have? Even removing unhealthy leaves will reduce the ammonia produced by decomposing organics.Water changes and reduce feedings.
I find that bba grows whenever and where ever it wants, low or high light. Keep fighting it with excel and keep making small adjustments to your lights/ferts until you hit the balance point.
