Hello everyone, looking for suggestions on what appears to be interference of some sort when testing CH. Is there a preferred method for testing for and or removing various metals to make sure I don’t have an issue. I can’t seem to go straight from red to blue with CH test even when following the fading endpoint test method. I always get purple first. Am I supposed to see any purple as it shifts colors? Do we assume metals at this point?
Thanks to this site I think I am beginning to get a handle on taking care of my pool. I think. My current numbers are listed below with some wavering confidence in actual CH.
Wanted to share that I have tested myself and as with most people I was interested in how my testing compared to local pool stores and as I was learning wanted to see how they compared to TFP. I tried multiple big brand pool stores. After seeing the wide ranging and sometimes comical test results I was given only proved to me that they just don’t offer a reliable service you can count on. I think I was 100% convinced when a “pool expert” bashed other stores testing all while giving me results ridiculously out of whack based on common sense and my own testing. She described the wonderful chemicals she could provide to “help” me fix my non existent problem. I made the mistake of mentioning CSI/LSI and she proceeded to explain how she worked for a builder for 5 years and then the pool store for the last 6 years and has never heard of either of those things. I couldn’t help but laugh and ask if she was serious. She was. I have only been a pool owner for less than 6 months and even the most basic research you come across this information. Lmao.
FC 4.5 (added a little boost of liquid after swim day)
PH 7.7
CC 4.6
ALK 70-80
CH 390-440 (I believe I get blue at 420)
CYA 70-80
SALT 3100
TEMP 72
Sorry for the long post, also wanted to ask about the support donations. Not that it is a make or break thing but is the discount at the TFP test kits site for a discount off of 1 item only or is it a discount off of total bill? Is there an expiration date on the discount like number of days to use etc?
