Awesome! Thanks for the responses and extended discussion. I was making some false assumptions and I think using too little DPD powder. I apologize for not finding that myself. Jblizzle thanks in particular for the extending testing directs which helped a lot. Not sure why it didn't come up...

I am trying to do the overnight chlorine test with my TFT100 but sometimes have a 0.5 - 1.0 variation each time I do the test. I've been doing it three times and averaging the results but I was wondering if there is some better more accurate way to do this test. The little blue scoop for the...

Thanks for the quick responses! I have muriatic acid already so I will adjust both FC and Ph immediately.

Hi folks. I had an algae problem about a month ago which my old pool service resolved with algaecide. After receiving lots of advice from folks here at TFP, I fired the pool service and been using bleach as my sole source of Chlorine. My pool has been sparkling since. As my CYA was at 100...

Thanks chemgeek. That is why I am firing them. There methold marginally worked under perfect condition but broke down completely during the long heat spell we had here in Fresno. They are fired and gone. I am BBB at this point. I tested the pool at 8 FC yesterday evening and added 96 oz 6%...

My test kit arrived. My numbers are: CYA 100 (matching pool service and pool supply store). I ran the test at 1:2 and 1:3. FC 8 CC 0 TA 100 pH 7.5 The pool store's readings a week a go were: FC - 5 CC - 5 pH – 8 TA - 90 CH - 200 CYA – 99 According to the CYA/FC chart I have a target of...

As an update, the pool has never been clearer, which only confirms that the pool service is not worth the money. What I had thought was clear before wasn't really clear at all. Its really amazingly clear now. I am hoping that I'll be able to keep it this clear myself using the BBB. I am...

Its funny but reading a bit more on TFP I found this thread raising the identical questions with the identical graphs! :oops: Here http://www.troublefreepool.com/more-about-recommended-cya-levels-t48502.html and Here http://www.troublefreepool.com/interesting-cya-article-t21910.html and here...

I am doing some research just trying to understand the chemistry behind the Chlorine / CYA chart and came across an interesting article. http://www.ppoa.org/pdfs/PrP_Cyanurics%20-%20Benefactor%20or%20Bomb.pdf. The author argues that CYA should be kept to no more than 20 ppm in a pool...

Thanks. I can't wait to get my test kit.

The didn't fix the "dead" water exactly. They drained it completely and refilled it. If I had a high cya wouldn't that cause my FC to stick longer once I got it up? I guess it doesn't really matter. The point now is that I'll have a kit soon and can figure out what is going on for myself. I...

Thanks! The pool company does run their service at CYA 100. He told me that they deliberately brought it up to 100 as soon as I refilled it. I think he was definitely lying to me about some things. The service only comes every other week, which makes me think that maybe the run CYA so high so...

He just tested and claims that it is at 100. He does not want to shock because he claims that shock won't h elp. He blames filtration. My filter was sucking air at a valve. now that the leak is fixed, he claims that fc of 5 will clear out up.
