What's your take on zeovit?

[The Codfather]

I started zeo almost a month ago. The results I am getting are noticeable, I could see results after about 10 days. Now my tank has been running for about 18 months, so I'm just dropping the levels. I'm only adding zeo back and start, with 3L of zeovit and carbon.
I also joined the zeovit forum, very very helpful. They get back to you fairly quickly, and after several pm's I was on my way down the rabbit hole.
My algae problem is almost completely gone. I tried prodibio before for several months without these results. Just my opinion and thoughts are that you have to find a system that works for you. For me, that's zeo.
