UP Aquarium Supply was the first to introduce an external in-line CO2 Atomizer model quite some years ago.
The atomizer D-508 comes in three versions 8/12mm 12/16mm and 16/22mm.
|UP Aqua D-508/16 has one 4mm connector for the CO2 supply and two 16 mm connectors for the installation on the external filter return pipe.|
|Comes with rest with two suction caps for attachment on the outside of the aquarium.|
|Instructions for use at the back of the retail box.|
Thank you for viewing.
