How large is your tank? I think 30% water changes daily is excessive unless your water chemistry is really poor. Do you know your readings (ammonia, nitrates, nitrites, etc)?
I replaced my 55 gallon tank about 5 weeks ago with a 135 gallon tank. As expected, I started to get a lot of brown algae. I bought 3 otocinclus catfish. Each is only 1 inch long. In 4 days, these 3 little guys cleaned off my glass and 1 large plant. They've started on some decorations and rocks. They are absolutely amazing. Do your homework before buying any, as they can be somewhat sensitive.
The algae should disappear, anyway. But these guys are so awesome, I want them in the tank even after the algae is gone. They can be feed with cucumber and zuchini slices.
