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

I love this. I'm always fighting with algae on the sides of my tank. This takes it right off with no scrubbing. Just be careful when using is in the corners. It's sharp edges will cut the glue in the tank.

Among the best value aquarium products out there. I have the expensive scrapers from Seachem and others. This thing works - not exaggerating - 10 times better than the expensive stuff. Don't bother trying the more expensive options - just get this and enjoy a clean tank that is fast to clean. It's THAT good.

Not only is this tool well made. It is hands down the be best aquarium glass cleaner that I have ever used Much better than the magnetic cleaner. Literally cleans the most stubborn algea spots with one swipe. The only manual tools that you need is this scissors and tweezers.

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 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.

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

This thing is freaking great. Of course, you have to be mindful while using this tool (like any tool), especially around seals, but with some common sense you’ll be just fine. I had this hard white scum/scale growing in my tank that my usual tank scrubber wouldn’t even make a dent in, and with this razor tool it peeled right off the glass and I didn’t have to stick my hand into the tank water. Definitely recommend using this right before a water change or you’ll have sheets of gunk in your tank, but the glass needs to be wet while scraping anyways so two birds/one stone. Just get it friend.

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.
