Great Scraper

This is the first scraper that I have used that cuts through coralline and the persistent green spotted algae easily. I have tried hand and other magnetic scrapers with less than stellar results - this one is the exception. I would have given this scraper 5 stars, but I had to lower to 4 after considering purchase price.

I used this product on my 220 and it worked good at removing all the hair and coralline algae that my tank had but it scratched the entire tank. dont know it it was the hard velcro type material that is in it or if it was the blade. either way my tank is very badly scratched after one use

Excellent Product

This product is a ....life saver.. in terms of corraline algae. i have a large bowfront tank, and using a normal mag-float, let alone a typical scraper blade was not doing the job. i love the fact that i dont need to put my hands in the tank whatsoever.

One OF My Best purchases

A great product. I use it on all 3 of my saltwater tanks whenever the glass gets dirty with coraline and that annoying green spotty algae. One of my best aquarium purchases ever. I'm still on the original blade after 6 months.

Love it!

This thing is awesome, It scrapes the coralline off nooo problem. Which is great, b/c we have a huge tank, and we cant get soaked every time we need to clean. I would totally recommend this everyone! It is great!
