I'm coming out of a nasty case of GW and Hair Algae and I want to clean off some of my equipment (heaters, filter intake/spraybar). The algae is fairly well attached and doesn't respond well to the usual soft damp cloth. I've heard of folks using bleach and H2O2 to clean. What's the best process for this cleanup without harming the equipment and fish/plants. What about driftwood ? I have a large piece that would probably take a 55 gallon trash to dunk it in.
