I'm very new to TFP and so far I have been very impressed with the knowledge of the members and the willingness to share and help others. Right now I am one of the 'others'. This is my 2nd full summer as a pool owner. This pool is approx. 30 years old and was left empty for two years before we bought this place. We filled the pool last summer after sandblasting and repainting with well water. I have been using pool store chemicals since the beginning, but I have grown tired of leaving the pool store with a sack full of stuff and leaving behind a lot of money every time I had my water tested. I just received my LaMotte ColorQ Pro 7 kit. I know 'now' that this kit is not endorsed by TFP, but I hope to get something that is endorsed in the near future. Here are my results from the first test:
FCL: 5.90
PH: 7.8
TA: 152
CH: 431
CYA:120 (Got this number from the pool store)
I entered this information into PoolMath and this is some of the recommendations: Add 34 oz. of muriatic acid. It suggests I replace 40% of water because of the high CH and to replace 67% of the water because of high CYA. Under Suggested FC Levels it says nonSWG minimum:9 target 13-15. Shock: 47 Mustard Algae Shock: 64. I am not sure about these last readings. I guess I need to know about the minimum FC and target as well as the shock number and the algae shock number. Thanks in advance for your help.
