Algae on plexi tank

[yellowbellied]

What do you guys use to clean/scrub all the algae that appears on the front of your plexiglass tank? I've tried using the Mag Float, but it only works sporadically.

An old plastic credit card works great.

Mr clean "magic earaser". only use the orginal ones as they have no deatergents..etc. I also upgraded from a mag float to a alage free hammer head, much better.
