Review on 🐠 Enomol Gravel Vacuum - Aquarium Water Changer and Fish Tank Cleaning Tool Kit, Universal Siphon Pump for Quick Aquarium Water Changing by Katie Ortiz

Three problems: drains slowly, almost does not suck, there is not enough information in the instructions. Expires, but very slowly. This method uses a lot of water to build up pressure to empty the tank - about the same amount of water is wasted as it is emptied. Let's take it back and find a more efficient method. My old squeeze siphon worked just as well (but my new tank is 90 gallons instead of 40 gallons, so I'll have to find something stronger). The suction power is definitely NOT enough to remove gravel. I took an empty tank with dust and small particles (very little) and tested on them. He barely sucked it in. Once you lose suction, it's difficult to put it back on. I had to turn the nozzle to fill it so there was no air in the hose and then turn it to empty for it to work. Plug in the adapter (do not force it). Luckily another user provided the information. I was really hoping this would be the answer.
