🐠 12pcs QMseller Stainless Steel Aquarium Fish Tank Air Flow Control Lever Pump Single Way Valve – Efficient Oxygenation for Healthy Aquatic Environment Review

This filter is a complete disappointment. It's loud, inefficient, and doesn't do much to maintain the cleanliness of my aquarium. I can't believe I wasted my money on this.

Good product. I've used cheap little plastic valves on my aquariums since I started the hobby and had to update after many of them broke. I will never go back to cheap plastic again. They are easy to install, good looking, accurate and inexpensive.

not work properly and air and let water through. So I bought this and it's sealed and watertight with a good ball valve control system. It's very small and does its job very well. Needed precise control for my custom foam soap dispenser and this metal valve works flawlessly.
