Pronetcus Algae Scraper for Glass Aquariums, Fish Tank Cleaner, Aquarium Algae Scrapers with 10 Stainless Steel Blades.

This is one of the best aquarium accessories I've purchased. It makes cleaning algae off the glass much easier than it was with the magnetic scrubber, which means the cleaning happens more often and the tank looks better. I'm impressed with the sturdiness of the handle, and it comes with 10 or so double-sided replacement blades. The blades are sharp enough to remove the algae without trouble, but blunt enough that they aren't dangerous. All around a well designed product.

This is what I needed. First off, when placing rocks in your aquarium, make sure to leave enough space between the aquarium glass and the rock. For what? To clean! I didn't pay attention to rock placement and developed an algae spot that I couldn't get to no matter what I used. I bought 2 different glass magnets to no avail. I bought a long sponge type cleaner, that didn't fit as well. After a year of ignoring it, I finally looked for something else. I found this. Guess what? No more algae spot in that tight space! I was also developing these algae spots that were really stuck on the glass and wouldn't come off with the magnets. This took care of it with ease! My tank is looking crisp now! Buy it for those difficult jobs.

I literally raved about this thing to a co-worker. I can't believe how well it works! I have multiple steel algae scrapers with different sizes that didn't work well at all. I also have the magnet scraper and the scrubber pad with a handle that looks like the green side of a sponge. All are inferior. This thing is unbelievable. You have to put the little scraper piece in but it comes with the tool you need to install it and takes a few seconds. My tank has never been this clean. I tried it on curved plastic and it kept getting caught, but scraped off some algea, so stick to straight glass and you'll be impressed.

Doesn’t clear algae in one scrape, leaves streaks but if you go at it a few times it’ll clear it all. Does its purpose, but with a bit of elbow grease. Not the worst tool ever, and has been helpful. Good size!

This really works, went from a green algae covered aquarium to crisp and clean in 10 mins, just turn off your filter and gravel vac all the floating algae

So far, this is the best scraper I've owned. The blades are not rusting nearly as fast as others, they are staying 'flat', so not leaving streak-marks...and have a nice wide path. Love it!

It seems like it'd work, but unfortunately the blade hole is way smaller than the piece it's supposed to attach to on the stick

Game changer! I'm not a professional fish tank person. I've attempted to have tanks before for my kids but cleaning is not easy. I've tried the magnet wall scrubbers but the algae holds tight. Not even my snail or shrimp can get the tricky spots. A razor blade is the only thing that worked for me but I hated putting my arm all the way in. It really disrupted things. This algae scraper makes it so so so much easier. It comes with several blades and a nice safety cover for when it's stored away.
