Mag Flip Cleaner?

Has anyone tried this on Coralline?

I know it came out a while ago, but dont remember what kind of reviews it had.

Im in the battle agains corralline and it seems to be winning

 

I tried the medium I believe and i would say its a piece of junk thats not powerful enough to scrape even light coralline off 1/4 inch glass, maybe the bigger sizes are better, or the new ones revised, because I got mine when they first came out, but I wasnt impressed.
your better off doing what one of my maintenance buddies did and taking a good magfloat and epoxying a scraper blade to it.

 

Any suggestions on what scraper to use. Then?

 

get the magfloat with the easy blade attachment. It works awesome you just have to be careful around silicone. I use the big magfloat and all I did was super glue it on. Easy Blade Algae Scrapers - Black - English

just don't leave it in the tank or the blade will rust! I dry my off after every use.

 

kent marine's scraper, comes with a blade (don't use it on acrilyc), gravel shovel, and soft scraper.
