Features

  • Powerful Magnetic Glass Cleaner, Get the Glass Clean and Quick: Compared with other aquarium cleaner that pops off due to inadequate magnet, our algae scraper has greater magnetism and easy to use. It securely holds onto the glass or acrylic surface, allowing you to effortlessly glide the cleaning brush along the inside of the tank. It can clean the soft algae in a single pass, and the tough spots after a few passes (in less than 5 min), suitable for tanks 1/4" to 5/8"(0.25 to 0.6 inch) thick
  • Detachable Aquarium Algae Scraper,Effectively Aid in Algae Removal: A notable feature of this magnetic fish tank cleaner is the removable scraper, which comes in two types: plastic one for removing natural sediments on acrylic aquariums, stainless steel one for scraping off tough algae and mineral attached glass tanks. Note: Use the blades to clean in the same direction towards the blade position, don't change the direction horizontally to avoid scratching the fish tank
  • Automatic Floating Design,Keep Your Hands Dry: The aquarium glass cleaner that goes inside the tank floats, so if you break the magnetic connection, you dont need to fish it out a bottom of the tank. This convenient automatic floating design ensures the algae scraper for glass aquariums is easily accessible without wetting your hand and prevent it from being lost
  • Comfortable Handle and Dual-Sided Cleaning Surfaces: Our fish tank cleaner is designed with ergonomic handle, comfortable to grip. It gives you more control over the movement of the cleaner, you just have to swipe it once and the algae is removed. The cleaner consists of double sided cleaning surface, one is velcor surface for scraping the algae off of the inside, the other is a felt pad for wiping the dust off the outside, make the aquarium is pleased to the eye from the inside to the outside

  • A must have for fish keepers!!
Size: L for Glass Thickness:1/4"-5/8"
Great glass cleaner!! I had been using an older store bought one for our 75 gallon but it was made for a smaller tank so the magnetization was not strong enough for the thickness of the 75 gallon tank glass so it kept popping off but did a fair enough job, I always meant to get a larger one but kept putting it off for some reason, fast forward to last week when I saw one of these glass cleaner+scrapper combos at a friend’s house on their tank and I was SOLD went and bought this one and I am SO glad I did! The glass was really dirty I wish I took and before/after but this tank looks beautiful again! Flawlessly and easily cleaned the algae off! I will be purchasing more for our other tanks in the near future!! ... show more

  • Best Algae Scraper ever.....but why did they make it white?
Size: L for Glass Thickness:1/4"-5/8"
This is such a smart design I wonder why every algae scraper doesn't float to the top. I never have to reach into the aquarium and pick it up off the floor. I love it so much. The only reason I am giving it 4 stars is I don't understand why they made it white. It gets dirty very quickly and it is difficult to clean. It is brown in no time and even if you clean it it looks dirty. Had they made it Black it would have been better because the algae would have been hidden a little more. I attached a picture after cleaning it. But the price was amazing so it is worth it. ... show more

  • Super Strong Magnet
Size: M for Glass Thickness:1/4"-3/8"
Works great, easy to use, effective, super strong magnet, good size (I bought the medium size 1/4-3/8 glass width for my 55 gallon fish tank).

  • Weak magnet.
Size: S for Glass Thickness:1/8"-1/4"
It is made well but my magnet is not strong and comes apart when using.

  • The fish keeperThid glass cleaner really does make cleaning your aquarium much easier!
Size: S for Glass Thickness:1/8"-1/4"
The fishkeeper magnetic aquarium glass cleaner arrived on time and in excellent condition. I ordered the small magnet for my 32 gallon Coralife BioCube. It did clean off the Coraline algae, although I would recommend the medium size magnet cleaner for these tanks. These tanks are made of very heavy tempered glass, and a stronger magnet would be preferable. I am going to keep my small magnet for smaller 10 gallon and 20 gallon tanks that have thinner glass. I'm very happy with my purchase. ... show more

  • Broken on arrival
Size: M for Glass Thickness:1/4"-3/8"
Got this today expecting to use it to clean my tank. I open the container and unboxed all the pieces which included the magnetic scraper, the actual scrapers, as well as an extra plastic piece. When reading the instructions i came to find the extra plastic piece was broken off of the inner magnetic piece, this piece of plastic attached the scraper to the magnet. I was extremely disappointed to have paid for a product just to find on arrival it was broken. One plus is the magnet is very strong as i tried the strength once i realized the product was of no use. ... show more
