Saw this tip on Guitarfish's blog:
How safe is this to do on the tank? Especially a nano (20 liters) with live inhabitants?
Every time you do a water change, pull the glass diffuser above the surface of the water. Pour enough hydrogen peroxide onto the ceramic disk that it keeps the disk submerged in the H2O2. As you’re busy trimming, scraping the glass, and filling the tank back up, that H2O2 is busy oxidizing the algae from the surface of diffuser. By the time you’re done filling up your tank, the diffuser should be good as new.
