Review on TUNZE Blades 0220 154 Magnet Replacement by David Amarelo

I have tried several brands of scrapers over the years and have always been satisfied until I bought a Tunze scraper which does an excellent job of cleaning even the most stubborn algae on glass. The only downside was that in the original packaging I only had a metal blade on the long side of the magnet and it only had a small plastic blade on the short side - mostly only suitable for acrylic cymbals. With the purchase of this replacement blade I now have metal blades on either side of the magnet and I now clean my glass by moving the magnet both forwards and backwards. Too bad I didn't know about this scraper 10 years ago when I first got into the marine hobby, it would have saved me a lot of time and effort.
