Found this of interest but when I checked it out on the website, I don’t see how it protects you from scratching the acrylic. If you get sand caught between it and the acrylic won’t the acrylic still get scratched?
No… the sleeve is a mesh that doesn’t hold the grain of sand between it and the acrylic pane. Of course, it is best to avoid the sand bed, but in most cases any possible scratches will be avoided.
I have had acrylic tanks for many years and some of my secrets to success are the magnet sleeve and also NEVER leaving the magnet within reach of any visitors/children that want to ‘help you’ by running the magnet all over the front pane.
