CO2 diffuser CUP

The CO2 diffuser CUP is an elegant accessory to the aquarium with CO2 to fertilize. The CO2 diffuser is quite compact and with the included suction cup to the glass of the aquarium to confirm. Made in different sizes for different sizes of the aquarium. The membrane produces bubbles of CO2. Place the CO2 diffuser in the flow to the aquarium with CO2 to fertilize!

Thanks to the small dimensions of the CO2 diffuser CUP is also perfectly suitable for a small aquarium. Also the bigger brother (CUP 30) is made of clear glass and will not detract from the aesthetic impression.

Comes with a transparent suction cup, and is to connect the CO2 hose 4/6 mm. It is advisable to make use of flexible silicone CO2 tubing.

CUP 30

Vorm van de CUP is minder dan op de foto weergegeven. Voor de rest is de glas redelijk dik, en gaat niet snel stuk.
membraan is van een gemiddelde kwaliteit, niet slecht maar ook niet een van de beste.
