Ideally the pH in a reef tank should be around 8.3 during the middle and latter part of the lighting cycle. Having an optimal pH is very important for coral health and growth rates. If you’re struggling to maintain pH or if your aquarium suffers from chronically low pH, connecting a CO2 scrubber to the air intake of your protein skimmer is a great way to increase and keep your pH levels within ideal ranges.

If you are struggling to maintain an optimal pH range then perhaps a CO2 scrubber is what is needed. In closed environments, carbon dioxide are elevated and this can contribute to lower pH levels in a marine aquarium. A MORE
