Water changes w/ aragonite substrate Q

[jiffy]

In my Ps. Saulosi tank, I have aragonite sand to raise the ph. My tap water is obviously not the same (I forget what it is exactly).

How should I handle water changes because of this?

Do smaller water changes, but more frequently.

This will allow the new water to be buffered without affecting the entire tanks water

Well for a start what are the pH values for tap and tankwater? If they're more than .2 apart stick to small (10%) and frequent, else you need to buffer the new water.
