Cabochon Ruby is a non-return valve made from quality Japanese glass and mineral close to ruby. Cabochon Ruby can be used indefinitely, and makes an elegant addition to your aquarium.

Once CO2 supply is stopped, aquarium water often flows backward into the silicon tube toward the regulator. If water enters the regulator, it may cause serious damage.

It is a durable and decorative glass made check valve. The valve is produced from a mineral close to Ruby, and it does not deteriorate from a long-term use. Moisten the mineral before installation.

    Very nice visually, but when it comes to functionality it is not so great. You are suppose to moisten the ruby with a little water. So far so good. But that water evaporates pretty quickly (in a few hours) and the ruby gets dry resulting in big variations of bubbles per second. It a pain to keep fill it with water. In terms of stopping the back-flow, it fails also (at least mine does). Water slowly goes down the hose bypassing the ruby i guess..
    Does anyone have a solution for stopping the ruby to get dry so quickly? Filling it with anything else perhaps?
