No I'm using the liquid from api

 

Try letting a bucket/cup of tap water sit out for 24 hours, then test the pH of that.

Alright thanks if that doesn't work can co2 lower ph I'm getting my setup today will it affect anything or my fish

 

The decor and/or substrate in your tank can definitely affect your ph spike. I would try and avoid any type of ph down additives

It shouldn't hurt your fish if the pH doesn't go down too quickly. It will lower your pH.
