Hydrogen peroxide as BGA cleaner upper...
I have read several messages lately, about hydrogen peroxide having been
used to kill BGA. My 3.5 gallon planted windowsill tank has a recurring
problem with a thick coating of what I believe to be BGA. The only fish in
the tank are a pair of killies. The main "inhabitants" are a few crypts and
a hygro. I vacuum it off; it's very easy to remove, not really stuck on
like most other algae. It comes off in sheets. I do lots of water changes,
and it always comes back with a vengeance after a couple of days. The
plants are continually being smothered by this icky stuff, and I thought I'd
try the hydrogen peroxide.
After reading about it on the Krib, the dosage for a tank with fish isn't
clear. It seems that 2 ounces per 10 gal was used with no ill effects in a
planted tank, but can someone recommend a safe dose for a tank containing
fish? Or would I be better off to temporarily remove the killies?
