All Jbj Regulators come with
All Combo co2 units come with the a ph controller sms 122 and the co2 regulator including the items listed below
Dennerle Check Valve - A very high-quality Dennerle German CO2 ( carbon dioxide )check valve for freshwater or marine applications. Secure compression fittings which takes 4/6 mm (ID/OD) or 1/8" airline tubing
CO2-Proof Tubing - Normal airline tubing can lose up to 20% of CO2 through its membrane. Silicone tubing reacts w/ CO2 and render it less efficient (thus the silicone hardening over time under CO2 usage). Our special CO2 Resistant Tubing loses less than 1% of CO2. Also perfect for saltwater use (eg: Kalkreaktor). Rated Class I for both CO2 and saltwater applications. Unlike other so-called CO2 Tubing which is rigid, ours is soft and flexible. Choose between transparent green, transparent blue and black. 4/6mm -ID/OD.
(PER FT) 12 ft minimum
Mode of operation: CO2 is a very volatile gas. It diffuses through the special diaphragm on top of the test container. There it diffuses more over the air gap into the indicator solution. The CO2 Visual Indicator has a particularly fast reaction, both for higher and lower pH values.
Technical data: YELLOW = too much CO2 / GREEN = right CO2 level / BLUE - too few or no CO2
For freshwater aquatic plant aquariums and ponds
