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

I use this scraper to reach down into the gravel line at the rear of the aquarium where BGA tends to develop. The extra long length is perfect for not having to stick my hand in the water. For general algae removal on the glass, I still use scrub sponges for that. It takes less time.

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.

I can clean my glass without getting wet. The fine blade is very effective. Wide blade means I can clean the glass in my 30cm cube in just a few minutes. Comes with a safety cover.

Awesome cleaner! Diatoms and algae slough off with ease. It will scratch your glass if you’re at too deep of an angle or it’s not flat on the glass, so take your time and don’t try to maneuver around obstacles like a heater. So much faster than using a scrubber. Feels well built and has no signs of rust after using it for a few months. Recommend!

Some products go the extra step, this one was designed excellent, comes with a screwdriver for removing the blade, and 10 extra blades, the handle screws together for easy use & break-down for storage. Highly recommend, got rid of my algae in the hard to reach places the magnet type scrapers can't reach!

Works really well for my 50 gallon tank

The blade makes all the difference. It’s not the usual square razor blade. This one is larger with rounded corners. I used to have to scrape up and down many times over an algae spot before it as cleaned. With this scrapper all it takes is one scrape and the algae is gone. Only thing I am not fond of is the tilt angle screw mechanism that seems somewhat weak/flimsy to me.
