question on PH

copying from a post a few minutes ago:
pH is determined by the alkalinity and the CO2 level in the water. The water, in turn, often has excess CO2 if your home air has excess CO2.
So ways to boost pH generally relate to bringing in more fresh air, or using up the CO2 such as with limewater or a CO2 scrubber.

Mine was at 7.8 as soon as we closed the house for colder weather. Didn't seem to bother anyone. As soon as I starting dosing 2 part the PH moved up but it was 7.8 from November till a few weeks ago and everything was going very well and no one seemed unhappy. You can find out if it's excess CO2 in the house by taking a sample of your aquarium water, putting the container outside, bubbling fresh air into it with an air stone for an hour and then testing the pH.
It is down at the moment, unfortunately.
I personally wouldn't want my tank routinely below pH 7.8.
If you cannot bring in more fresh air, limewater (kalkwasser) is a good option.

Randy would that increase KH as well?
Yes, limewater adds calcium and alkalinity in an appropriate ratio to replace what is being used in the tank. It has the largest pH boost per unit of alkalinity of any supplement.

If that will increase KH, would that be quite dangerous for the op tank assuming he got a high kh reading? We don't know what is his kh level as he did not provide any...but assuming he got 9 dkh, would introducing limewater will risk increasing kh more than necessary?
It is usually not a problem to add limewater. The increased pH increases demand and few folks get excessive alkalinity from dosing limewater since it is limited by evaporation. I can't actually recall any just now.
Get it, its a must
