Re: CSM+B mixture is cloudy
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.
Do you have the ratio of vinegar to solution?
For example: 5 ml of vinegar for every 250 ml of solution.
Also, I assume you are using white vinegar.
