OK- I am a total newbie. I have been viewing this site for a while and am trying to absorb all of the info I can. I purchased Leslie's DPD Deluxe test kit and realized that I got the homeowner version not the service version. (significantly less $$, BTW). This kit does not test for CH or CYA. Do I need to buy another kit so that I can test for these levels regularly?
Any and all help will be appreciated.
