Zeovit has been disappointing to me thus far. I get THE worst film algae on the glass and for the first time in my tank history, I'm constantly battling hair algae and cyano in certain areas of my tank, and bubble algae/valonia continues to grow. This AFTER starting Zeo.
It requires a fair amount of diligence, I've found, and I'm growing weary of the effort that returns no positive results.
I've been researching other carbon-based nutrient-low systems and am intrigued by
this. I understand the risks, but it looks much less involved, yet effective.
What do you all think?
