Review on 🐠 4-Ounce Kordon #37344 Methylene Blue for Aquarium - General Disease Prevention Treatment by Brianna Quintana

Not sure about 'flavor' and 'stability' but heck, 5 stars anyway. I know this stuff has saved some of our freshwater fish that already had a fin or fins in their aquatic grave. You need a 'hospital' aquarium to use methylene blue as it will kill plants and snails in the concentration needed to treat your fish. A simple 10-gallon aquarium will also do. Depending on the extent of the spread of the fungus, it usually takes one to two weeks for it to go away completely. (Make sure the fungus is completely gone before stopping the treatment). Thanks to methylene blue, some of our largest and oldest fish are still alive and swimming. The Black Spirit had a severe fungal infection a few years ago when I first heard about methylene blue; Thanks to Revane's one-day confinement, I was able to start treatment quickly and he made a full recovery. Our ancient angelfish lost an eye to a fungus but otherwise made a full recovery.
