Needed a new leaf skimmer so went to Leslies. I have been testing my own pool for 2 years now thanks to TFP. Periodically I bring a sample to them, always good for a chuckle. Numbers are usually close, but this time not even close.
Leslies My TF100 numbers from this morning
FC 4 9
CH 275 460 (not from today, but has been over 400 for the last year)
CYA 10 (!) comment "low" (no kidding) 60-65 (not from today but has been 60-65 a month ago and most of last season)
TA 120 40 (just dumped in the only small box of baking soda I had to raise TA, need more)
PH 7.5 7.2
TDS (what's that?) 3400 comment "high" ????????
A rare cloudy day in Tucson so measuring CYA is out but I am going to re-measure the other numbers in a little while.
My numbers are consistent with what I measured a few days ago.
I suspect they do not use our FC test and 4-5 is all they can measure.
No explanation why their TA is so far off, or the PH
I suspect the CYA is off because they only had fluorescent lights to see the dot and it probably disappeared quickly. Because of the low CYA he even asked if I used just bleach. To his credit he did not try to sell me any pucks or stabilizer (though he probably should have if he believed his numbers) but their test sheet recommended it
Sorry, loses the spaced format when I post, my numbers are he second one in each line
