Review on 5-in-1 Aquarium Gravel Cleaner Water Changer Glass Scraper Fish Tank Sand Wash Pump Kit with Air-Pressing Button and Adjustable Water Flow Controller Clamp for Effective Fish Tank Gravel Cleaning by Tracy Pederson

This item is amazing, has great suction and is very easy to start with the push of a button. Has an extension that is not in the video. I've used it with both sand and gravel and it works with both. I used to use a hose connected to a siphon, but it's a lot easier and faster, plus I don't waste water and don't lug the hose around my house. It also makes it easier to clean my tanks that aren't very close to the faucet.
