🐠 Neptonion Algae Scrubber Fish Tank Glass Cleaner Brush - Floating, Scratch-Free, Non-Slip, Magnetizing Review

I use this on my 55 gallon tank. It's easy to use, won't scratch the glass, and the magnets are strong enough not to be accidentally knocked out.

Strong hold. Almost 3 inches off the glass and it's still holding up. Love this product it didn't scratch my topfin 10g tank either would buy again. I got a small one.

I have a small tank (less than 5 gallons) and it has worked great. It detaches from the magnet if you hit the top, which isn't glass, but that's to be expected - it floats and you don't have to put your hand in the container to reattach it. My tank is bent and still works great.

I love this handy little device! Great magnet that cleans the pool very well! It'll take a few passes, but now our tank is sparkling clean! I bought the smaller size and it fits our 150 gallon tank perfectly. I gave the job to my teenage daughter and she pulled up a chair and got to work! She really looked like she was enjoying herself!

I recently started two aquariums. When I was looking for brushes for interior cleaning, I came across this magnetic brush. I confess I bought it basically because it seemed like a really cool idea. After using it several times I can say I'm glad I chose it. It does its job well and even makes cleaning the tank a pleasure! The magnet is very strong. I recommend!

I was impressed by the strength of the magnets. I was afraid the bond wouldn't hold with the aggressive motion to remove the algae from the jar, but it did. It didn't get it all, some of the stains were stubborn even on a fingernail so can't wait for this to do more and not ruin my glass. The soft surfaces didn't hurt, and the two pieces stayed connected even in the bent corners. Will buy again if needed

Works great. The material of the outer part of the scrubber feels like felt. I have a second piece of felt that I place between the handle and the glass for added protection and cleaning. The material on the inside of the scrubber (which does the actual scrubbing) has small bristles, like a thin brush, like the hard side of Velcro. I prefer bristles to flat cleaning material because the bristles don't "catch" debris and risk scratching the glass. The magnet is strong enough to achieve good…

I like it a lot! At first I thought we could clean the seaweed jar by hand or some kind of sponge. But after a while we couldn't resist! So I bought this guy (size small). Just unbelievable! Sticks so well (we have a 20 gallon tank) and holds up great! Even if I hit something and it goes offline, all I have to do is "follow" and the pieces will reconnect. The edges are so smooth that it is very easy to move them from side to side. Heavier growths require cleaning, I may have had to go over the…

I used this product as soon as I received it. I bought the small version. I have a moderate amount of brown diatoms growing on the tank walls and plants. I intend to use it with a 15 gallon Fluval Flex tank and originally intended to leave it hanging in the tank between uses. The first thing I noticed is that it sticks to the glass walls of the tank pretty well. The Fluval Flex glass tank I have has a straight top and bottom. The back is a wall separating the built in tubs from the rest of the…
