I am looking to increase the water flow in my aquarium in an attempt to eliminate bba. have an Eheim 2217, a HOT magnum filter and the Hagen elite mini (niko's DIY co2 reactor). How many powerheads should I have in a 55 gallon aquarium and what would be the ideal flow rate?

I have 4wpg with lighting at 7hrs a day. I haven't measured the co2 level but it's approx 1-2 bps. I don't have any test kits and I'd rather not go out buying all of them.
