My tank runs about 7.8pH. When I mix up my water, TM Pro Reef, it comes out to about 8.2pH. I did a small water change yesterday, just to have a gallon of old aquarium water to dip some new corals in today.
When I add the new saltwater, the tank comes up to around 8.0pH for a short while, then drops back to 7.8pH.
The old water is in a bucket on the floor in the same room, with a lid sitting over the top, not sealed tight. I checked the pH this morning on that bucket of old water, only thing running is a heater set to 78 and a small powerhead. The pH in the bucket of old saltwater is 8.2pH and the tank is 7.8pH.
Why is it dropping in my tank, but raising back up when sitting on the floor? I'm trying to wrap my head around this one?
