Hello all,
I'm thrilled to finally make my first post to what has been a wonderful resource for me for months!
While I had great plans to fully document our pool build in Oceanside CA on TFP all along the way - somehow that did not happen and the build was completed last month, but I will post some pics anyway of various stages in another thread.
I found TFP well into the process - and was immediately sold on the methodology embraced here. Although the build process went really well I would have done a few things differently if I had learned more earlier in the process. No regrets, happy with the end result and where we are now, just would have done a couple things differently from the start (I will post those in a different thread and speak to the PB interactions to hopefully help those at the start of the process).
First I just want to say thank you to all the folks that take the time to post and respond sharing information and knowledge - this is so valuable to us lurkers who are trying to learn about the process and the myriad of decisions along the way to building and spec'ing a new pool.
Sorry for the long intro - now on to my question:
> like many newbies I had some trouble interpreting the CYA results. Since I had the TF100 kit, it comes with a 50PPM +/-5 R-7065 standard to train one at reading the results. When I use this material (performed test twice with same results), the dot does not disappear until around 25PPM (see photos). I attached 2 photos, 1 showing the vial filled to the 50PPM line and another showing the appearance of the dot with the camera held at eye level and the vial at waist level at 50PPM. Am I doing something wrong or is there possibly something wrong with the 7065? My own pool water shows a CYA of around 60 with the dot totally gone and 70 with it gone-ish. Since i recently switched from the PB installed Fusion2 to a SWG I am trying to get my CYA to SWG levels (70-80). I have not added any CYA yet, the level it is at is from only the PB pool service trichlor tabs they used for the first month (1 pail - about 8lbs). My most recent test results are below:
TF-100
FC-4.5
CC-0
pH - 7.3 (I did this on purpose this morning to reduce TA - will raise with aeration, was at 7.6 B4 I added more acid to get to 7.2 per pool math)
TA - 90 (still trying to get this down to 60 before going to Borate in the future, was at 100)
CH - 275
CYA - 60 (or 70 depending on how gone the black dot is supposed to be)
Salt - 3400
Thank you for any input,
Scott...
