I opened my thermos of CSM+B today and discovered that it had a strange haze floating in it. I have put the recommended amount of Excel into the mixture to prevent mold. The mixture is kept in a stainless steel thermos so no light gets to it. My question is has anyone experienced mold in their mix even after using excel?
yep i get fungus even when adding excel to the solution, next time add some vinegar to the solution, you can also add ascorbic acid and potassium sorbate to keep the solution fresh and fungus free.
