We’ve used 3% over-the-counter Hydrogen Peroxide with Angelfish eggs. Never squirt directly on the eggs. Just in the tank itself. I think we did… 1 ml / 1 gal. Discus are touchy though. The H2O2 might be bad for their slime-coat. Methylene Blue is commonly used, but I’m not as familiar with it’s affects on Discus.
