If you're the owner of certain delicate species like goldfishes or have older fishes, you would know they might be sensitive and reliant on a steady environment with the right CO2 levels and water direction. Any change in these elements could cause them stress. This is why having a sturdy and reliable check valve is of utmost importance.

Rhinox High Quality Brass Check Valve is made from brass, so it doesn't bend, break or rust like plastic check valves might. Simply install it correctly by making sure the arrow is pointing in the right direction, and use tubings that have 4mm inner diameter and 6mm outer diameter. Rhinox Check Valve has proven to be anti-leak, anti-backflow and is consistent in providing aquariums with keeping water flowing in one direction.

Note that Rhinox High Quality Brass Check Valve is made for CO2 systems and not air pumps. For the best results, follow the instructions and ensure your fishes live a happy, healthy and stress-free life!
