GULFSTREAM TROPICAL AGU125MED Mag-Float Glass Aquarium Cleaner, Medium

A bit pricey, but worth the money

It does the job, sort of. Gets rid of algae, sort of. Yes it floats if you happen to lose the magnetic connection. It's a bit big so struggles with the hardscape in the aquarium it's in and the magnets are too strong for one of the smaller tanks. I bought a razor scraper too with was cheaper and more effective.

Have used this product for years and decided to buy another to replace my old one. They're incredibly well made and clean the glass beautifully

Excellent product. Does exactly what it is supposed and does it well. I could have got by with the smaller one but it's all good.

Brilliant really strong magnet cleans the tank with ease

ok thanks

I have owned three previous versions of this style of magnetic glass cleaners and unfortunately, this has been the worst. Yes, it floats, yes it is strong and holds together tightly on the glass. But the design on the inside magnet is terrible for collecting fine stones from your substrate. Result - I now have three deep scratches on my aquarium. Never had this problem with other brands so I can only assume it is the 'lining' on the inside magnet.Others may not have this problem if their substrate is 'thicker/larger' but if you have a sandy substrate then watch out.

Total waste of money. Just buy a scraper.
