Review on 🧼 Gulfstream Tropical AGU125MED Glass Cleaner for Mag-Float Aquarium, Medium Size by Holly Hunter

I have it on a 54 corner tank. It does its job with dust algae, but anything harder just stays there. And even getting rid of soft algae will take a long time. Large size causes a tsunami in the tank, you move a little faster. Year if you trust your wrist, the two sides part. So you have to be careful anyway that it stays very parallel to the glass. I've tried it on my 125 gallon and it barely works there. The glass is too thick for a magnet and obviously unable to really clean the glass. In general it's not bad but not great and for the money it should be.
