Review on 🐠 Revolutionary Marine MicroMag Magnetic Glass Cleaner: A Game-Changer in Aquarium Maintenance! by Roy Cook

Shipping took me 2 attempts to get my magnet (from 2 different sellers) so there must have been some confusion. The magnet product itself (1x1) is great and I would recommend it instead of the piranha algae cleaner (4x2). It's very small and perfect for Nano. The algae cleaner works great and it only took me 1-2 passes to clean the glass. However, I will say that if you press the magnet on the outside of the glass with a Jay (a polishing magnet marked "Innovative Marine"), a small amount of adhesive will remain on the glass. I removed these stains with a microfiber cloth. As I said, it's great and works as advertised. However, note that you may need a microfiber cloth to buff the outer glass. Also a tip: don't use Windex to clean glass, you don't want ammonia near your tank at all. I used a spray bottle filled with water to square the glass and buffed it with a microfiber cloth.
