Best Magnet Algae Scraper for Biocube Rounded Corners?

[TiltedReef]

Hey Everyone! I have a biocube and cannot seem to find a product of magnetic algae scrubbers which can reach the algae on the glass on those pesky rounded corners. Any suggestions?

I have two lines of algae on both front corners that completely beat my flipper and will end up having to manually scrape with a sponge stick.

Thanks!

Mr. Clean sponge, or a melamine sponge.
Although i hear some Mr. Clean sponges are no good, so do some research.

They work absolutely wonders.
