The pH in a reef tank should be around 8.3 for optimal coral growth. If you’re struggling to maintain pH, or if your aquarium suffers from chronically low pH, connecting an IceCap CO2 Scrubber to the air intake of your protein skimmer is a great way to increase and keep your pH level within ideal ranges. The IceCap Color Changing CO2 Absorbent Media is included.
