Hello Everyone –
I’m new to the forum from Plano, TX. I had the pool installed in 2004 and am just now getting TFP-religion. I’ve read through all of the pages in Pool School, and am ready to use the TFP program. Here are my numbers per a visit to Leslie’s yesterday…
FC – 1.5
CC – unknown
TA – 120
CH – 180
CYA – 30
PH – 8.0
Salt – 3000
I’m planning on getting a TF-100 test kit asap – is that sold at retail stores, or only via mail-order?
My current problem is that I’m getting yellowing on the walls of the pool. It started in late May – we had a fairly wet spring. Leslie’s kept telling me it was being caused by so much rain water displacing salt water. On the weekend of 6/1-2, I shocked it with 3 bags of Leslie’s Chlor-Brite, added CYA to get it up to 30, and added salt to get it to 3200 (pool mfg recommendation is 3200-3400). We had 40 13-year olds in the pool on 6/7 and it looked great – clear water and clean walls.
Went out of town on 6/13, pool still looked great. We returned on 6/24 to yellow walls. On 6/25, I brushed the walls and shocked again with 3 bags of Chlor-Brite. Water now looks great, but walls began to get yellow again on Friday 6/28.
Leslie’s told me the following yesterday when they gave me the test results – chlorine level is OK, add Muriatic acid to reduce PH (done – added 48 oz), add CYA (done – added four lbs of granules). Some of the info in the Pool School pages has me wondering – can you please calm my fears on the following –
The Target FC levels in the Chlorine/CYA chart are much higher than anything I’ve seen – will this make the water harsh on the eyes and skin? Also, will the SWG be able to maintain those levels (once they get that high) or will I need to regularly add chlorine?
Are there any potential problems with using bleach to shock, given the fact that I have an SWG (I noted that the “Recommended Levels” page in Pool School has separate levels for “bleach” and “SWG”)?
The Pool School page titled “Water Balance for SWGs” has some different info and figures on it compared to some of the other pages – is this page the baseline for me to follow, given that I have an SWG? If so, should I try to work on all of the figures at once – or try to get each item to the correct level one at a time? Is there a particular order to follow? And how long should I expect it to take to get everything in balance?
Will it be difficult to get TA down to 60-80 while keeping the PH no lower than 7.5? And what is the best way to do this?
Should I wait to get my test kit before doing anything else?
Sounds like adding Borax would help, based on a couple of forum threads – do you agree?
I’m alarmed by how low my CH is – should I fix that right away? Is there a common hardware store chemical that I can add for CH, or do I have to get this at the pool store?
