The scraper blades work well for removing algae from both glass and acrylic surfaces. The sponge is gentle on the glass and doesn’t scratch. I changed the blades after a few months of regular use and found them effective.

I used the stainless steel blade on my glass tank and it removed stubborn algae without damaging the surface. The plastic blade worked well on my acrylic section. A simple and reliable tool set.

Great replacement blades. Easy to install and the sponge helps with light buildup. I’ve used them for over a month and still see good results. No scratches, just clean glass.
