getting rid of black brush algae

My tank's been infested with bba for the last 6 months. I've been reading the advice on the board off and on and kept my nitrates and phosphates at the recommonded ratios for 5 months straight with no change. My last attempt I added a large mass of fast growing floating type plants to consume nutrients but it didn't seem to slow the growth of bba down at all. In the last 3 weeks I thought I'd try to starve the algae of phosphates and stopped dosing it bringing the levels down to .1 for the last 3 weeks. The algae still thrives, no better or worse. Nitrates are still between 5 to 10 and the plants are all growing really well but so is the algae. BBA is really the only algae problem in the tank.
46 gallon
3 watts per gallon
pressurized co2 at 30ppm
nitrates between 5 and 10
I dose 5 ml flourish iron twice a week
5 ml plantex twice a week (1 tbsl per 500 ml)
1 teaspoon pottasium at water change
1/3 water change once a week
ph 6.8
gh and kh on the low side
I've heard a few people mention that using flourish excel seemed to get rid of their bba and was curious about that. I have some on order and will probably try it. I need to find some siamese algae eaters also. The only algae eaters i have are ottos and amano shrimp. I've heard of the bleach dip method but it would be very difficult to dip everything in my tank, the algae spores are probably everywhere. I also have considered the copper treatment. I've tried to order the azoo brush algae killer but it is only sold in australia. I really just dont have many more ideas and would certainly appreciate any advice anyone has on getting rid of it.
