The CO2 diffuser mini CUP is an ornate accessory for the smaller aquarium with CO2 to fertilize. The CO2 diffuser is quite compact and on the edge of the aquarium to hang out. The membrane produces bubbles of CO2. Place the CO2 diffuser in the flow and you have an ideal situation in a responsible manner in the aquarium with CO2 to fertilize!
Thanks to the small dimensions of the CO2 diffuser mini CUP is perfect for a small aquarium. Made of glass, it will not impair the aesthetic impression.
Only to connect with flexible silicone CO2 tubing (4-6mm).
