Sort of just a PSA for those thinking about getting a mag float glass cleaner for their aquarium - it doesn't work that well. I purchased the glass version and it didn't clean the glass very well..AND I now have 2 new scratches on the glass
- and yes, the magnet was clean (brand new). The one for acrylic aquariums might do better.
The cleaning surface is very abrasive (like the hard plastic loops in velcro) and they are spaced quite far apart, therefore leaving streaks of uncleaned areas. My old Hagen magnetic cleaner does a far better job at cleaning the glass without adding scratches, because the cleaning surface is like a nylon felt surface. It doesn't float, but it does the job well.
That is all....
