I have my 72 Gallon Bow front tank. I have been getting some purple cyano on top of my rocks on both sides of the tank. It seems that the flow there is a little low. I have my MAG12 return pump and two maxijet 1200 one in each corner. Should I get two smaller powerheads and make a spray bar and point it down so that it creates more flow or should I customize my my existing ones with
spray bars also.

picture three gives you a full picture of the tank. Wow it looks bare compared to now. Anyways the tallest rock on the left had purple cyano and the tallest rock on the right. Any ideas on what I should do to improve flow in that area?
