Took a sample to pool store just to compare.
Pool store readings My test results
FC 3 2.5 CC0
Salt 2100 2900 instant reading on SWG
CH 300 200
CYA 35 50-70 depending on when its read
TA 120 110
PH 8.0 7.8-8
Wtr temp 67
Volts when gen. 29.4V
Desired % 50
Now we have had a ton of rain here in N. Texas. I have pumped out 2-3 times at least 2-3" of water each time.
-My TA over the course of a year has stayed pretty steady between 125-110
-The PH test the first time I did it when I got home was 7.2, I poured another sample of water and tested again 7.8-8, tested one more time with 7.8-8. Not sure why the first test was low. This happened the other day also.
-The CH has been on the avg for a year around 260-200
-My salt reading obviously is a lot lower than the beginning of last years season when the pool was installed at 3400 becasue of all the dilution and water loss due to pump downs.
-Due to the lower salt level even though it satisfies the SWG and the lower water temp right now. Would this explain why the SWG at 50% is just maintaing a 2.5FC. Because 4 days ago at 76 degrees my FC was up around 4. Should I bump my salt level up to the middle of the scale , say 3200? Obviuosly temp affect everything. THe cell amps was at 2.84 at 76 degrees.
-Should I raise the CH up to around 260 since 200 seems to be on the bottom minimum level?
-Opinions on PH test not reading the same on first test?
-CYA reading. The 70 reading was just as the black dot was getting hard to see. 50 was when it had disappeared. So which reading do I take?
Thanks so much for all the input in advance. This site has gotten me thru 1 year w/o any issues at all. I have learned so much in 1 year.
