Water ph

[successnowhere]

Hi SRC, I jus bot a American Marine PinPoint ph Monitor, after calibration, my tank water only measure at ph7.5.

Don't know why so low? Must I wait for a few hours later for the measurement to be stable?

If really so low, what step must I take to increase the ph to 8.2?

Tks

I use buffer to get my PH to 8.2

Is it Powder form? So its normal for tank water to be below 8 if did not add in any buffer is it?

Yes because distilled water is neutral pH (7.0) so quite normal if adding water that is not buffered

OIC cos I normally use distilled water daily to top-up my tank.

So need to buy buffer powder to slowly increase it liao.
