We're talking a few mm of acrylic here. Not an issue. Acrylic has a high transmission ratio, better than glass. The difference between 1/4" and 1/2" is negligible, even up to 1" is still not that...

This is of major concern to the reef aquaria. You do not want these magnets to be exposed to the water. They need to be sealed.
with any scrubber, wait until you get a mature screen before changing anything. That's likely several weeks.
So you took the magnet out of the molding?
