Carbon (VSV) dosing volumes

[Aquattro]

For me, Zeovit worked well for years. Apparently. VSV dosing daily, not so much. I've given it enough time now to show results if results were coming, and I now believe they are not.

Unfortunately for me, I know the problem, but the solution isn't an option. So I need an alternate solution to the secondary problem. And I need a shorter zeo reactor.
