ADA Cabochon Ruby (Check valve)
The ADA Cabochon Ruby is a durable and decorative all-glass check valve (no-return valve) for the CO2 supply system, made from a ruby-like mineral that does not deteriorate with long-term use. It prevents aquarium water from flowing backward into the silicon tube toward the regulator when CO2 supply stops; always use it in an upright position.
