I would like to use hydrogen peroxide instead of
malachite green in hatchery
against Saprolegnia, and in ponds against Ichthyophthirius.
Would somebody suggest me the concentration and the length of treatment?

This is an excellent idea and an environmentally
responsible decision.
Prevention dose on eggs is 500 ppm for 15 minutes every other day or for
treatment use 500 ppm for 60 minutes every other day. Dose in ponds is
usually 100-200 ppm for up to 1 hour every other day. The fish
treatment should be watched very carefully because of the oxidative
character of hydrogen peroxide. You can also use formalin for these
treatments, this is also an environmentally responsible treatment
(formaldehyde is a widely distributed naturally occurring substance).
Usual dose for egg fungus treatment is 1000 - 2000 ppm of 37% formaldehyde
for 15 minutes repeating as necessary. In ponds the usual dose is
170-250 ppm (of 37% material) for 1 hour. Treat every 2-3 days until
parasite is controlled.
