I didn't read through this entire thread, but from the first posts you have dual T5 HO tubes over a 20g so this is a lot of light, and thus algae will continue to be an issue. If you could use only one of the tubes, and floating plants, you might manage. I see it is not increasing as fast, so progress is being made which is good.
When you mention fertilizer in the previous post, you call it Excel comp, I will assume it is actually Flourish Comprehensive. You might try twice weekly, with this much light.
