For what it's worth, I completely solved my diatom/brown algae problem with an albino longfin bristlenose pleco, and by adding PhosGuard to the tank filter. My 75 gallon tank had been plagued with brown algae from the start, for over a year. Can't say which one of these had the biggest impact, but I have watched the pleco vigorously munch the algae off the plants, glass, and gravel. When the tank is looking particularly clean, I'll toss in a few algae wafers and the pleco likes those too.
