Review on 🐠 MingDak Aquarium Gravel Cleaner Vacuum Siphon Pump: Efficient Water Changer & Gravel Washer with Flow Controller and Long Nozzle - BPA Free by Scott Adaymiln

Very easy to use and very effective, you can't go wrong. It makes tank cleaning an easy project, my two youngest sons really enjoyed using it. You stick one end in your fish tank and the other end in a 5 gallon bucket or so, then there's an inflated section of siphon tubing that you just squeeze 5 to 7 times and all the magic happens right before your eyes. With a great gravel stop that lets through debris but not rocks.
