Since finding this site in April, and listening to all your great advice in getting my pool squared away, i have had nothing but pristine water to swim in for the last 2 months. As a matter of fact, I have turned four people onto this site and the test kits after they swam in my pool. Originally, I bought the Taylor K-2006 test kit, and have been using that since April. However, I was running out of reagents, and went with the TF-100 with the XL option (next paycheck I am getting the Speedstir!). When the TF-100 came, I ran tests on my pool with amazingly different results from the K-2006. I noticed that the drops on the TA, FC, and CH tests were a lot bigger coming out of the K-2006 droppers than the TF-100. I ran the tests 3 times with each test kit to ensure I wasn't screwing something up, wiped the tip off after each drop, and this is what I got.
K-2006:
PH: 7.5
FC: 4
CC: 0
TA: 70
CH: 180
CYA: 40
TF100:
PH: 7.4
FC: 8
CC: 0
TA: 150
CH: 320
CYA: 30
I then tried the OTO chlorine test (K1000) and it checked out with what the TF100 was reading. All I had to test TA, CH, and CYA were test strips (6-way HTH ones, which I know we all despise, but I had no other way) The strips matched up more to the K-2006 readings. My PH is perfectly happy at about 7.4-7.5 and only climbs when I use a fountain to cool the water. Since this is the case I figured my TA had to be closer to what the K2006 tester said.
Sorry for the long winded post, but I am curious if anyone else had noticed this, and which one I should believe more. If the TF100 is accurate, I have been over-shooting my target FC, because the K2006 was coming back at half of what I actually had.
All of my test supplies (yes including those horrible test-strips) are kept in a cabinet in my laundry room, which is air-conditioned.
Again, I really appreciate all the help and knowledge I have received since finding your site. My pool store actually called me last week to ask why I haven't been in in two months...I told them I found much better pool professionals to listen to!
thanks,
Don
