I would agree with you if the testing was accurate. I have proven (at least to myself) by taking the same water sample to multiple stores and getting vastly different results from each.I buy my chlorine and acid at Home Depot.
I buy my conditioner at Leslies. I pay too much for it. But the fact that I have them test my water for me for free, I respect the fact that they have bills to pay too.
Really. $30 a year to a company that tests for you and asks nothing in return except that you spend a few bucks in their store?
But that's just me. I don't mean to offend anyone.
So here is the test, three samples of water, all taken at the same time. I tested one at home and took a sample to each store. The only difference was drive time for the tests.
My Results:
FC 10
pH 7.5
TA 75
CH 210
CYA 100
Store #1 Results (BioGuard automated testing)
FC 10.3
pH 8.0
TA 160
CH 173
CYA 104
Recomendation - Acid to reduce pH
Store #2 Results (hand tested with Taylor chemicals)
FC 5.0
pH 7.6
TA 125
CH 350
CYA 90
Recomendation: None
I was amazed also. I find the range of CYA between 90 - 104 fairly acceptable. The last time I did the multiple store test (when my CYA was 200+) the place with the 90 reading had me at 90 then. That must be their "too high" reading. The place showing 104 had me at 130 last time. I don't find it acceptable when it is 200+ and they are giving me low readings.
Store # 1, again a BioGuard store says CYA is "acceptable" 30 - 200ppm, says chlorine should be 2 - 4
Store # 2, again a ProTeam Pool Products store says CYA is "acceptable" 30 - 100ppm, says chlorine should be 1 - 3
So, chlorine 3ppm with 100 CYA - What am I going to have?
But, both wished me a good day, didn't try to sell me anything and told me to keep doing what I'm doing.
They do have to keep the lights on, and I can agree that with their "seasonal" business there needs to be a slightly higher mark up. I can live with that. But I don't want to get robbed every time I go in the door. I recently needed a replacement pool light bulb. On line $14.99. Pool store $39.99. I was ready to pay $5 or even $10 more for the convenience. When I questioned it all I got was a shrug of the shoulders and take it or leave it. And, that was from the manager - not some kid they hired for the summer.
If it already hasn't started, I'm sure there is soon to be a shift in the pool store model. The younger folks (and some of us old folks) are quick to jump on Google for second opinions. The pool store has to change and adapt.
