Works like it should. A few swipes back and forth will clean you right up. I keep mine in the tank in a corner under a plant out of the way. Good stuff.

This scraper worked wonders on the glass of my 5.5 gallon aquarium. It made the glass crystal clear. It’s more time consuming than a sponge. But i found it to be a little therapeutical using this scraper, as it gave me extra time to look at my fish while cleaning.

I can see the Betta swim his own way That's right That's right There's no algae in the way

Gets very little muck off. The magnet needs to be stronger to really have any effect.

I thought this would do a better job and be easier to use, but I was wrong. It just smears stuff around and what it does remove just goes right back into the aquarium, causing more of a mess to clean up. Obviously you have to pick it up and move it from side to side and you cannot get into the corners, where the algae builds up the worst, so I do not recommend it.

Strong enough, but the scrubber pad is basically the "hook" side of Velcro, and didn't take off all the algae film in one swipe on my saltwater tank. You have to go back over the same spot several times to get the glass clean. A magnet scraper with an actual blade would be better.

Too small and weak for my 20 gallon tall. Keeps losing magatize, then have to use my arm oe net to fish it out. Did little to scrub off algae. A new scratchy sponge worked way better. Was good for kicking up gunk in the gravel for the filter to catch. Maybe a large one would be better

I got it a few weeks ago and I'm happy I did it works well
