I saw these today on the JL website. I was wondering if any of you had devised a way to make something like this yourself??

I have a 60 cube tank and the top of it is about 6 feet off the ground so it can be very tricky to clean that sticky dotty algae off with a magnet cleaner.

I have been known to clean the tank by hand with an exacto blade but that takes me over an hour and my clownfish like to bite!!!!

Ideas?

or has anyone ever used an easy blade??
