Aquapro Algae Cleaning Brush

You can use this fish tank cleaner to suck away aquarium dirty water and move the gravel tube to clean the gravel or install the duck-billed suction head to clean fish tank feces. It’s not electric, only use the water pressure and siphon to drain or fill the aquarium with fresh water. With the pressure from the water, the gravel and sand can be sucked up into the gravel tube to vacuum out the debris in the gravel. It does the water change quickly and neatly. It comes with a 15/16″, M21, 3/4″ copper metal faucet adapter that fits on most faucets. Each pack comes with a 15/16″ copper threaded faucets adapter (large diameter: 23.8 mm), an M21 copper threaded faucets adapter (large diameter: 21 mm), and a 3/4″ copper threaded faucets adapter (large diameter: 26.4 mm).
