This works better than I ever imagined. So easy too - even a caveman can do it. But seriously, this has made a pain in the butt task so much easier. This even works on a biocube with the rounded edges. Thanks Corey for mentioning it on one of the videos - I would have never tried.
Snaps right onto the Mag Float. Really easy to use.
This is a life saver. Keeps my tank so clean
Do not know why I waited so long to get this. No more razor blades and wet arms trying to scrape green spot algae.
Packaging and shipping is excellent as always.
