Works great. if you have a lot of plants, corals or hardscape not glued/epoxy purchase a better quality magnet. It does work great bust shakes and vibrates a lot due to imbalance in magnet. This causes disturbances effecting aquascape.

Scratch the glass And it's very small for the price

Very disappointed in this product. Doesn’t work nearly as well as I’d hoped.

I have a 65 gallon tall and I’m 5 feet tall. And this works amazing for the layer of calcium that tries to build up in my tank. I clean It performs it crystallizes. I used It for my mother’s tank as well. She has a 60 gallon as well, with brown and black algae on the glass. This thing cleaned the glass effortlessly!! And guess what, if you aren’t satisfied, you can always take it back and get a refund!

This is a good strong magnet that does a good job. The star deduction is for the overall size. It’s a bit small to be called “large”

The magnet is super strong and holds together very well while using it to scrub the walls of my aquarium. My turtle is still unsure of just what it is when I use it lol

Great product, well made and blade is great quality Stainless steel. Sharp edge removes film off glass with very little effort

It's the simplest little Gizmo but for the amount of time that we spend cleaning algae off glass it helps speed things up tremendously and does a good job at the same time
