Yes, 29 is that much stronger than 3. The only tank I know of doing this is using 25ml of 29% in about 100g volume daily.

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).

Treating the frag plugs worked. Only need to do it for 5 minutes, though. Algae on the plug turns white and rescinds in a day or two. Frag itself is none the worse for wear. Beats trying to manually scrape off the algae or move the frag to a new plug every few weeks.

But will not dose my entire tank with peroxide. No need for that... A little algae here and there gives it the "natural" look and keeps my tangs busy.
