I tired it immediately and the magnet is super strong.SUPER STRONG! Works great! I used the large size for a 55 gallon tank and it's perfect!

This algea scraper is amazing. I had some very tough algea that I could not get off with a regular pad. My tank is very deep so it is hard for me to use pressure down near the bottom to scrub. This magnetscraper got it all in one shot. You just need to be careful handling it as it can snap on your fingers if you are not careful.i love it!

I have 50 gallons plastic tank with very difficult access to the walls because the top of it had small openings (keep my opinion about tank's designer for myself). So I could not clean walls practically at all. And not it is just a matter of minutes. It cleaned my very dance algae perfectly. And I practically did not even have my hands wet. Highly recommend

Another must have for tank owners! This is perfect for in-between cleanings! The magnet is extremely powerful so I would be careful w/children playing around with this.Slide smoothly across the tank when in use.

I am using this in an acrylic tank. Works Ok but due to its size and uneven thickness of the acrylic glass of my tank there are some spots where I have trouble. A smaller unit may have worked better for my use case. But all in all a good product

This one is big. I got it for my tanks 125g and up. Works perfect. Cleans the algae and crud off the inside and outside of the glass. Floats so you don’t have to stick your hand down in the tank to get it out. Def gonna buy more for the smaller tanks.

It's fantastic at doing what it's intended to do. I use it on 10 gal, and 36 gal bow front. No issues. I read reviews where people broke their aquarium glass while installing on tank. You must understand manet's and how they work. Just follow the directions for putting on and off the tank, and all works great. I'm hoping this one will last at least a year. If so, I will continue to purchase this awesome product as needed.!

This is agood aquarium glass cleaner for its size and price ,I have a 55gal tank and it cleans the glass fairly well this magnet could be a bit stronger but for the price it did a good job.

Definitely good size and a very strong magnet. So strong that it pinched my finger twice now. Almost afraid to use it because it hurts when they happens! It is as described and cannot fault it but take extra care while using

I have a 29 gallon rectangle tank and I bought the smallest size this seller has and its a good size for the tank. If you had a larger tank I would go up a size. I checked the pads over closely before using to make sure there were no sharp spots so I did not scratch the tank. (none were on it) the outside piece is nice and soft and the inside piece feels like the pokier side of loop Velcro. I was a little worried about the inside scratching but it did not. The magnet was strong and I could get…

The magnet is stronger than competitors, it floats unlike some competitors, and is cheaper than most of the competitors. Very durable and cleans well. Highly recommended.

I was hesitant on purchasing this item because of the scratching of glass issues that these have. I have a 30 in deep acrylic tank and only the really way to get the inside " glass " clean was to go swim’n.This thing is wonderful.cleans the inside with little effort. I clean the very bottom edge with another telescopic tool I have to avoid getting scratches from the sand.this is a must have item.

Perfect for occasional cleaning of my aquarium glass. Removes algae effortlessly and does not scratch the glass That's my feedback!

I have a 90 gallon corner bow front tank, this thing is almost to large for it. I may get the smaller one as this one can't clean between the glass and some rocks/driftwood in the tank because it can fit. Great product, just know the larger one is for very large tanks with nothing near the glass.
