Methylene blue

[bhaminal]

Hi, does anyone have experience using Kordon brand methylene blue? 

Also, im slightly confused, some of the co-op videos talk about being hard to get now a days, but it looks available online through a variety of vendors. Including in a 1 gal option! Am i missing something, or is the concentration/ formula different now? 

My sterbai are starting to mature and spawn, would like to have some on hand to prevent egg fungus’ing. 

Thanks!

I used it on mine.  Let me grab the thread for you.  I have very, very similar questions.

In other countries it was likely a lot more common and is a lot less common nowadays.
