NANFA-- hydrogen peroxide

I've used it occassionally in my planted tanks as a last resort or annual
it has worked on resilient brush algaes along a piece of drift wood i
have... the main idea as i see it from the Aquatic Plants Digest topics on
this are that it does in fact deprive the algae (and bacteria) of oxygen -
thus the bubbling... and it dies (or seems to.. most surface algae will grey
or disintigrate w/in a day or so)
it has not been suggested for film and or diatomous algae though such as
green water to my knowledge..
id suggest it only as a temporary method though.. since i tend to believe
that attacking the root problem of the algae is the best recourse..
(nutrient deficiencies or excesses)
but this does work to help a problem area get beat down quickly..

care is needed in the useage since it will super saturate the area around it
w/ oxygen you dont' want to OD your fish as some have done in past

a quick search of the APD archives at
will give you more than enough info on this topic

good luck..

There may be something to it. My thinking (not original) is that the
positive effects of the peroxide on the redox is enough to allow other
"things" to out compete the algae. The particular purpose of my inquirery
is to see if it would have an effect on bluegreen algae. I am willing to
try it, however I am trying to establish a dosage.
