I've been looking everywhere for Kordon Methylene Blue to use for my corydoras eggs but it seems to be out of stock on every website I've visted. However, I noticed that Bulk Reef Supply labeled it as discontinued in this link: https://www.bulkreefsupply.com/methylene-blue-kordon.html. Has the product actually been discontinued or has COVID stalled production and/or shipping? If I can't use this anymore, what else can I use for my corydoras eggs to prevent fungus? If it helps, I have trilineatus corydoras breeding in my 20g and I'm using a 1/2g with a sponge filter to hatch and raise the fry since I have so few eggs.
