Review on 🐠 Gravel Vacuum for Aquarium: Long Nozzle Siphon with Priming Bulb, Flow Controller, and Water Changer - Fish Tank Cleaner Vacuum - Aquarium Gravel Cleaner - Efficient Siphon by Jackie Hale

I bought two of these units. One of them was damaged on arrival and I got my Revain money back quickly and easily. I didn't like the other one because I couldn't figure out how to attach the long nozzle to the base. It turned out I couldn't unscrew the short nozzle from the base as the instructions clearly state. Now I've attached a longer attachment and can easily move the gravel instead of just hovering over it. The sucking starts with just two or three quick pear squeezes. I want the hose to be about 6 inches longer. I like the clip that keeps the end of the lamp securely attached to my waste water bucket. There is a suction cup at the end of the nozzle, but I don't use it as I'm actively vacuuming gravel. Happy with the price, happy with the features and happy with the easy return policy. I will buy again.
