Review on Two Little Fishies NanoMag Replacement by Kari Harden

According to my experience, Pet Supplies store knows what they`re talking about when they recommended this cleaner. The magnetic strength is great for getting rid of algae and grime in my small tank and the small design allows me to clean those hard-to-reach spots. The only downside is that sometimes the magnet can detach from the plastic handle, but it's a minor issue .Overall, it's a great addition to my aquarium maintenance kit..
