Raising PH in water change

[las]

My display is 8.3 PH give or take. I dose Kalk for calcium/alk//ph. The salt i use for water changes mixes up at around 8.0. What is the best product to use to get the mixed water up to 8.3 to match my displays ph? Im Curious what everyone is using.

Assuming your alkalinity level is the same then the difference is probably related to co2 in the makeup water which you may not be able to reasonably address. Aeration through a c02 scrubber may raise it.

In any case personally I would say the best approach is not to have any concern at all about it. A 20% water change may drop it from 8.3 to 8.24 initially at the most and likely will not last long long. Unless you are one of the very few who are sucessfully keeping their ph pegged at a constant value then your PH is going to be going up/down a lot more than that anyway through the day.
