First test results with the PS234

Thanks for the suggestion, off to the hardware store I go. One more question on
the high Alk. I just started using the PS234 this year and have not measured my alk in the past. I was wondering what causes the high alk? I have an automatic cover that obviously was closed all winter and I was closing everynight last summer, could this be a reason fo the high alk or is there anything else that may
have caused it?

Check your fill water, it may be high in alkalinity.
