another report of test dips:
strength: a 25% solution of H2O2 in salt water, 1:3 ratio of h2o2 to salt water
dip: removed frags from the display tank and dipped into this solution for 5 minutes
specimens: 4 frags of zoas/palys
results: in 48 hours, all zoas/palys look fine, they're open as usual, and ALL hair algae is gone. This is much more than my previous dips with lower solutions -the rock is wiped bare of hair algae, unlike the lower strengths, where lots of tufts were left after much of the hair algae fell off after a dip.
