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!
