I'm new to TFP and a new pool owner as we recently purchased a home with a 12,000 gallon IG with a Cartridge filter. I want to get off on the right foot and not be reliant on the local pool store so that I can effectively keep the pool balanced and well maintained. That being said I recently took some water samples to the local pool store and got the following results:
3/26/2016 4/2/2016 Free Chlorine 7.1 13.4 Total Chlorine 7.6 16.4 PH 7.0 7.4 Total Alkalinity 27 43 Calcium Hardness 264 293 Cyanuric Acid 231 205
After the first sample I was told to shock the pool which I suspect drove the FC up to 13 with a CYA over 200. I'm looking to get some advice as to what I should do (if anything) in order to get the chlorine and CYA levels back to recommended level (told you I was new to this). In any event, I wanted to open it up to the TFP community for any advice/wisdom.
