Methylene blue

    I am looking at getting some methylene blue to use to stop my angelfish eggs from growing fungi.

    My angelfish are not good at looking after their own eggs so i always have to take them away but most of the eggs don't hatch because of fungi etc.

    Will methylene blue help?
    Is it easy to use?
    Do you dose the whole tank or just the eggs some how?
    Will it hurt other fish in the tank?
    Anything else I should know?

    Hi, I just read on another post of someone using one milliliter of hydrogen peroxide per 1 gallon of water to combat fungus

    1. Yes absolutely its primary use in the fish hobby is fungicide
    2. I've only ever used the liquid, its as easy as measure and drop in
    3. You dose the water the eggs are in
    4. Yes, it will stain Permanately anything non fish related, but the tanks themselves hold up pretty well.
    It will also kill off you biological filtration
    Its pretty easy and safe to use. I imagine you can get the powder form online, but im not sure how to mix it, thinking about doing that myself, ive stained enough carpets and clothes.

    What I do with my angel eggs is remove them to another tank and dose meth blue with a sponge filter setup. It really helps with the spreading of fungus between eggs.
