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

I've tried using it and no matter what I did the suction wasn't enough for more than a small trickle. The pump bulb is in an awkward spot, allowing you to pressurize, suck, and move the hose at the same time. I even had someone help me bleed it while I was trying to clean it but I still couldn't get it to work. It was a waste of money and I had to buy another gravel cleaner from a local store to get the job done.
