I have been reading TFP during the process of building my pool and I purchased the TF-100 before construction was complete. When the pool was handed over to me it had extremely low CYA (about 5 ppm) and low CH (about 110). The Total Alkalinity seemed high, but I believe (from reading on here) that is a bit less critical and the process of changing it requires a bit more effort than some other adjustments. I added calcium and CYA last week. I have made no attempt to change the TA. I tested today and I have these levels (tested with TF-100):
Free Chlorine: 1.5
Combined Chlorine: 0.0
pH: 7.7
Total Alkalinity: 115
Calcium Hardness: 325
CYA: 35
Salt: 5200
Temperature: 53°F
Based on this, I have a few questions:
1. Is the TA anything to worry about?
2. My salt result seems high but the pool store tested it at 3,300 ppm. (a) Are there any common mistakes I could be making with that test? (b) If Salt is really 5,200 ppm do I need to be concerned? (I tested twice, several days apart, with the K-1766 Taylor Salt Test and got very similar results).
3. My SWG turned itself off because of the low temperature, so I am currently using 3" tablets (in a floater) for chlorination. I'm assuming that will continue to raise the CYA, so I am not planning to deliberately add any additional CYA for now. This is just my temporary solution until the temperature increases and the SWG kicks on. (a) Are there any concerns with this approach in general. (b) Do I need to consider adding more CYA (I previously used the granules in a sock method).
Thanks in advance for any input or advice you can provide!
