Pearling or excessive CO2?

Are you sure your test kit work? Try test distile water from guardian or watson, it should be around 7 for pH and 0 for kH.

Good question and a good suggestion. Yes will definitely get it and test it. Otherwise will be wasting my time doing further test with a defective test kit. Thank you Shadow for your timely intervention.

Sorry. Not counted if you don't use a pH pen
