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

Cleans MUCH better than siphon hoses - much less residual dirt floating in the tank. A superior design that uses the Bernoulli principle to create a powerful vacuum and remove dirty water from the tank to the outside or to the sink. I didn't think I would use inflation valves but they have proven to be very helpful. Several water source adapters are included, but the only minor issue is that the hose adapter thread pitch isn't standard US size, but it works if tightened to just a quarter turn. I plan to look for a suitable adapter as this product works so well.
