As for your lighting, what wattage bulbs are they? It sounds like you have TONS of light, which could very well be a big part of the problem. I'm also trying to fix a BBA problem. I only have 2x 39W T5HO on my 30 gallon, ~4'' above the water level, plus a glass top, which impedes light and decreases light intensity. I still have PLENTY enough light for growing the light-demanding stems that I have and my glosso carpets with no problem. I have my pressurized CO2 turned up to about 2.5-3bps. I use EI dosing with the same fert package you got. I have tweaked with a number of things including rinsing out filter sponges, increasing dosing, slightly decreasing dosing, and nothing has seemed to fix the problem causing the BBA. I don't know the PAR reading at the substrate, but I feel pretty confident it would be in the high-very high light range, and that's with only 2x 39W T5HO. I can't imagine how much 4x T5HO would be. My next step is to drill new pin holes in my canopy so I can raise my light another ~2'' (my light is a DIY 2x T5HO that is mounted as a shelf inside my canopy). I think too much light might be big part of the problem, or at least it's definitely not helping your situation.
I think you're right. +1. I battled two algae outbreaks for a whole month and won! Only to have the BGA and Hair algae start slowly coming back.

I think my two 10w Compact Fluorescent Lights (CFL) are a little too bright for my 10g low-tech planted tank. However, I think I could fix the algae permanently if I could get organic nutrients out of the water. It is also within the realm of possibility that I'm still dosing too much Flourish Comprehensive. Plant mass is also a little low after the algae debacle.

Pic: Recent, I doubt you can see the algae giving me problems now. Sorry, bad pic...
