Best scraper for Acrylic tank

[takayan]

I am having a problem to clean my Acrylic 150 gal tank. I bought MugFloat, but it is not strong enough to clean firm algae on 1/2 inch Acrylic tank. Do you have any suggestion?

Personally I'd stay away from algae magnets with acrylic. Thats just me though and my opinion. I started out with acrylic tanks (atm is located in vegas) and every tank I had got scratched eventually, no matter how careful I was. Kent scrapers with the acrylic blade works really well. If you must use a magnet get a algae free Tiger shark.

Hi Drae,
So you recommend Kent scraper, but not any magnet cleaner?
