Mag-Float Scraper Blades - Small and Medium Sizes - 2-Pack

Michael H.: It's exactly what I needed to clean my tank with and if there's anything more after trying it out I'll be updating my post.

anonymous: These blades work well to remove spot algae from glass fish tanks. They are easy to attach to the mag-float. They also do not scratch the glass of the tank. Even though they are called blades, they are fairly blunt, so it's unlikely that you'd cut yourself.

Anonymous: The media could not be loaded.  The Mag Float on its own does a decent job cleaning up light algae on the side of the tank but it struggles with anything more stuck on or in tricky corners. I've found this does a really great job easily lifting that stuff up so far. I would imagine with really tough algae crud you'd still need a traditional blade scraper, but so far this is taking off everything in my tank easily. It's very satisfying how easily it lifts off.

I wasn't sure if it was safe to leave the blade in the tank due to the possibility of rusting so I contacted Mag Float customer service and got this reply: "If you decide to leave your blades inside your tank we recommend changing the blades every 3 to 6 months due to rusting. However if you take out your blades after every use you wouldn't have to change it till about a year or so." I am planning on leaving it in the tank and just replacing the blade if I notice any rusting. With the blades being stainless steel I am not expecting this to happen very quickly.

Amazon Customer: Not easy to put on and take off. Doesn’t clean everything so I’d say this is just fair nothing great.

Eric: Worked very well for scraping off algae. However, I didn’t notice at first that it was scratching the living you know what out of the glass. Which was pretty disappointing for how well it worked. Also now my aquarium is all scratched up. I stopped using it after that.

Jason dugas: Great addition to the magfloat. Really good at getting the algea off your glass

YoWaddup: Scrapes real good. Recently had an outbreak of cyanobacteria. I got rid of it with blue-green stain remover like always (great product btw) but it always leaves what I'd describe as hard polyps on the glass. Even in death cyanobacteria is troublesome. The mag float just glides over them which is impressive given how coarse the brush is. The scraper attachment can take them off in 1-3 passes. It's also great for the boarder between the substrate and the water (though I would stay away from that boarder if you use fine gravel, sand or any substrate that can scratch glass. It's easy to accidentally drag some behind the blade) It did not scratch my glass, but I wasn't worried that it would. I wonder if those that scratched their "glass" have acrylic aquariums. DON'T USE METAL ON ACRYLIC. They do make an acrylic blade though. It doesn't beat a well made long handled scraper when there's a lot of buildup to deal with but for regular cleaning it's the best. The more time you can keep your hands out of your aquarium the healthier it will be.

Matt K: The Mag-Float Scraper works as advertised. It has made removal of stubborn algae much easier. Just be careful near the silicone seal.

Adam: Where have you been all my life. I have a mag float and adding a scraper attachment to it made a night and day difference. Pro tip, keep the scraper out of the substrate. Cuts through algae/diatoms like butter.

Michael F: If you have a mag float or are thinking of getting one get this. We have a curved 30 gallon tank that sits close to an open windows so it would often have algae issues. When we put on the attachment you could see layers / rolls of algae flake off with each pass. Super easy maintenance.
