I have used hydrogen peroxide before, I didn't go by a certain ml per gallon or anything. I have used for cory eggs, I put them in a small catch cup with about two cups of water and added four drops of the hydrogen peroxide. After 24 hours I take a turkey baster and suck out half the water, replace with fresh water out of the tank, and add three more drops of hydrogen peroxide, then leave it go. If IO do see unfertilized eggs, I remove with a pipette or turkey baster. I have seen on here that @Fish Folk has used it to, so hopefully they will chime in as well.

We use H2O2 on some eggs - rams, angelfish, Acara, corydoras. Our “rule of thumb” is 1 ml. / per 1 gal. Since we use 1/2 gal. specimen containers, we use 1/2 ml. We dose ever 12 hrs for 3x doses. We do not spray directly on eggs, but just into the water allowing the airstone to spread. We have overdosed once or twice. We use over-the-counter 3% H2O2. Also, we are starting to add one thumbnail sized piece of Catappa leaf and one or two alder cones to cost tan is and fight off fungus. We know a few breeders who actually stick a neocaridina shrimp into their egg container because they eat unfertilized eggs.

I also have been putting neo shrimp out of my cull tank in with the eggs

Do you use adult shrimp? Or younger ones? We've got a small but thriving batch of Cherry Shrimp that we'd like to try this with. Killifish eggs take forever to hatch (14-21 days) and fungus over easily. And our last batch of Cory eggs also succumbed to fungus . . . (mostly because we got lazy)
