Review on 🐠 AQQA Rechargeable Gravel Cleaner Kit for Aquarium - Powerful Fish Tank Siphon Vacuum Cleaner, Portable Automatic Water Changer, Adjustable Flow Rate, Energy Saving Wash Sand - 15W, 420GPH by Cara Ulfass

Hello, I have a 160 gallon aquarium. I bought this device to use as a vacuum cleaner to clean the bottom of the aquarium. If you look at the photos, you get the impression of a device that can suck in water and dirt, collect it through hoses and pump it out again at the other end. Unfortunately, this is a wrong impression. The pump is designed to have small holes around the suction rotor that clog instantly. When you install sponge filters, they immediately fill up and clog. Again, this cannot be used for medical and large tanks. This device is just a pump. Can only be used to pump water, not to clean the floor.
