View Full Version : Raising pH in a reef aquarium

Having kept reef aquariums for years, I was always trying to raise the pH in my reefs. Adding kalkwasser or running refugium at night helped, but I had other issues with my refugium and eventually gave up on kalkwasser dosing, so for a while my pH had reverted back to the lower range - it would raise up to 8.3 at the end of the day but would come to 7.8 at night. Sometimes the pH would be even lower, usually when there were more people in the house or during hot/cold seasons with less air circulation. I did get used to it, but recently this had changed, I wanted to share my findings with the rest of the community:


I've been using this monitor (any CO2 monitor will do) for the past 2 months and my results have been stellar - my pH swings are now fully dependent on the reef light cycle and no longer get out of sync.
