How long does the CO2 media last?
This depends on the size of the skimmer and the amount of air being drawn. The lifetime of the media is about twice that of Activated Carbon. You can expect the media to last from 1 – 3 months in most applications. Even longer for smaller skimmers. Does it affect Calcium/Magnesium/Alkalinity levels? The CO2 SCRUBBER will not raise alkalinity levels. However, if you regularly use carbonate buffers to raise alkalinity, the CO2 SCRUBBER will make these additives work harder. You may find that you can use less alkalinity buffers. There is no affect on calcium or magnesium levels. How do I know when to change the CO2 media? The CO2 media has a color indicator that causes it to change color as it gets exhausted. It is important to understand that unlike color-changing RO/DI Resins that change color when exhausted, the CO2 media changes color during its entire lifecycle. It starts out a white color and will turn a pale blue fairly quickly. The media will continue to change to a dark blue/purp
