Stainless Steel Algae Scraper Cleaner with 10 Blades for Aquarium Fish Plant Glass Tank

I have had these tiny tufts of green algae pestering me for years that my magnet took... well more time and effort than I was willing to give to clean off.This scraper removed all of that in one pass usually.I have been using the one plade for sever cleanings with out a problem. No scratching. But you should be aware that this could easily scratch your tank. If you chip or nick the blade on a rock that can cause scratches. and use the blade with even pressure, dont try to use a corner of the blade. I also am worried about accidentally hitting the silicone and oof that could be a wet mess quickly, so I just leave the corners dirty.And the build quality is great, I have no Idea how anyone has broken one of these by using it with an appropriate amount of pressure. Which is like no pressure, once the razor is flat on the glass the sharp edge just lifts the algae off, no need to scrub or flex the blade.Great buy and a must have for any glass aquarium owner!

I was surprised at how heavy and well built this is. It takes quite a bit of elbow grease to get the blade to conform to the glass surface well enough to not leave streaks of algae behind, but it handles the stress well without bending. I'm not using the blades that came with it because they are regular shaving blades with rounded corners that take away from the usable width of the edge. I ordered different replacement blades to use instead. They are made for scraping and have a wider cutting edge to remove more algae per pass. There are two minor drawbacks to using this tool to scrape algae though. It tends to chatter if trying to scrape downward, so pulling is the easiest way to remove algae. However, unless you pull the algae upward, remove the blade from the water and physically wipe it after each pass, which is time consuming and tedious, you end up with a bunch of free floating algae in the aquarium which effectively helps it spread and reseed itself everywhere. In one tank, this caused the water to turn permanently green and water changes wont fix it, so now I have to use chemicals.Replacement blades more suited to scraping than shaving:https://www.amazon.com/gp/product/B071CLJ3RT/

Would’ve been a 5 star if it was attached to a shorter handle. Kinda hard to use on stacked tanks with small room. But it works great on tanks that aren’t stacked where you have loads of room to maneuver.

How can a pandemic cause algae you ask. My 60 gallon freshwater tank (with two large Oscars and five Silver Dollars) is in my office. In these days of isolation I am home much more and the tank's fluorescent light is on many more hours. Thus more algae and also a desire to take on some small home projects,I used a scrubber with little result. Then I considered tablets to do the job, but the "fine print" says remove the carbon filters for about six hours or they will neutralize the tablets. For me that is a risk. Last time I changed both filters at the same time (I use a Biowheel 350 HOB filter) the water chemistry changed radically and I lost almost all my fish. Possibly I could keep the filters in my small tank. But this simple tool does the job with no chemicals. I did some scraping today. A little more tomorrow and the next day and almost all the algae will be gone.

I have a 55 gallon and 10 gallon tank, neither of which currently has a pleco to clean it. I've used single blade razors by hand but it's very inefficient especially in the large tank. This tool has enough reach and is plenty strong enough. You don't need a lot of force, just patience. The blades that come with it are paper thin, and I followed the recommendation of someone else on here who had a link to some heavier gauge blades. They work really well. The one hassle to this scraper is that mounting the blade can be very tricky. You're trying to align two holes in three sheets of metal, one of which is razor sharp, and then set two small screws before it all shifts apart again. I found it helps to hold the tool so the sheets are horizontal, then use a pencil to align the holes and set the screws. A vise would be a good idea.

The media could not be loaded. I can't begin to stress how much easier this has made water changes! Every water change I scrub at the glass. (On this tank I do it roughly every two weeks). This was after exactly 2 weeks. The green algae on my glass is nuts in this tank. And this scraper is just a godsend. It gets into all the edges, and harder to reach places. And just slides the alge off like butter. It blew my mind, and was immensely satisfying.I used it immediately upon receiving it. I took it apart and dried it well after use (based on some other reviews of rust). So hopefully this lasts me a long time. I can't recommend this enough, to anyone suffering with this algae!

I purchased this item because I had a plastic one that I had purchased from petco but I needed something a little more sharper To clean the algae off my saltwater tank glass. I only gave it 3 stars Because 1. the blades are a very thin and double-sided whichMade me a little nervous when I was trying to put the blades into the handle. Which wasn't easy.2. Lack of a safety cover to put on the blade once I was finished using it. If you need to store it away it can be very dangerous.Once I tried it out on my glass. I was satisfied with the performance.

I just used this for this first time and I am so happy with it. My 120 gal had algae caked onto the glass at the gravel level and the sides toward the back. I could not get to it with the magnet cleaners and the brand name with the green scrubby pad was not getting the job done. I was worried that I would just have to live with the look of the 2-3 inches of algae around the gravel line. This cleaned it off so easily and quick, I was really amazed and happy. I see the same type thing from lots of sellers, but this came with the 10 blades plus one on it already. Handle is nice and long and solid metal. A must have to clean the glass of your tank. I'll buy another for my other small tank.
