Have heard Dietmar (Hillegom) and others talking about peroxide for some time, so decided to give it a try. Keep getting algae on my frag plug bases on the rack, where the tangs can't get at it very well.
So got some 3% at the drug store and mixed it 4:1 in a small container and dipped a frag just up to the base (not the whole frag) for 10 minutes. Just over a day later, the algae all turned white and the frag is none the worse for wear.
Will do a few more the next few days. If this works, sure beats trying to clean algae off the plugs every few weeks (or at least that's when I should).
Am not ready to try H202 in the whole tank, as am concerned about maybe killing too much other good algae (the kind that live inside corals).
