Product Manuals & Documentation

Part #: 7074/2

Oxygen is very important for aquariums because oxygen is the air that fish breathe - just like humans. This is why circulating oxygen - also called oxygenation - is very important in fish tanks. Fish should have an adequate and constant supply of oxygen to be able to breathe normally.

As much as oxygen is important, carbon dioxide (or CO2) is important in aquariums, too, especially for aquatic plants. Plants use CO2 during photosynthesis. Without sufficient CO2, aquatic plants will not be able to thrive for long underwater.

Aside from that, CO2 also lowers pH to the ideal level in which hydro-carbonates can be dissolved to calcium molecules. Calcium is used up by corals when they form their exoskeleton.

Given the importance of CO2, it only makes sense for you to get the Tunze CO2 Controller 7074 for your aquarium. This device monitors closely the pH level of your aquarium and makes sure it is set on an ideal level. It also closes or opens the CO2 valve, depending on what is necessary, to control the amount of CO2 in the water. The valve is coated with nickel so that it won't corrode even when underwater. The Tunze CO2 Controller 7074 from Pet Store can work side by side a calcium reactor to enhance the dispersion of calcium in the water.



The Tunze CO2 Controller Set (7074/2) consists of pH Controller 7070/2, CO2 valve kit 7074.11 (including power supply unit 5012.01).

The pH controller precisely monitors the pH of the aquarium and opens or closes the CO2 valve as needed to ensure precise dosing of CO2. The 12 Volt CO2 valve is nickel-coated to prevent against corrosion. Great for use with calcium reactors or freshwater CO2 injection systems.

TUNZE® digital measuring instruments have been developed especially for the use in aquariums. The instruments with their electrodes operate at a high accuracy and are comparable with laboratory instruments in quality. The clearly arranged operating panel with key pad and adjustment buttons ensure fast and practical handling. The controller comes with parts for two different types of wall mounting.

Easy to set up Product Review by LUIS TODD (Posted on 11/29/07)

Excellent!

Comments: This pH probe/CO2 controller works like a charm! Easy to set-up right out of the box, just had to calibrate the pH probe with some distilled water and presto; continous pH monitoring! and CO2 delivery to the Ca reactor when pH levels are high enough.
