I run the magnet everyday. Not sure how some of you go so long between cleanings. My tank is pretty low nutrient and everyday, if you look at the front glass through the side of the tank there will be a slight,clear haze. You'll only notice it if you look through the side as you're running the magnet.... Does make a difference in the clarity of the glass IMO
Yep, exactly the same can only see it when looking through the side and my nutrients are very low. It's just a film but I like it spotless.
