Can I do a red slime treatment on a zeovit tank?

[Slick Fork]

I'll bet it's the macro you're trying to grow that's messing things up. I had a similar problem to the one you're describing. I was running a refugium in addition to the zeovit and had slime algae issues everywhere. Following advice on the zeovit forums, I killed the refugium, cut back on my dosing (the zeofood I cut back by 50%) and since then I haven't had any cyano issues worth mentioning. Maybe try disconnecting the tank with the kelp in it.
