Did you check your fill water before adding salt? My fill water (aka tap water) had 680 ppm salt.

He won't bite.

Thanks and congratulations

Thanks, the first PH number was a guess since it was off the charts. The pool is 35K gallons, the length is over 50 feet, I took a water meter reading before and after filling it; the deep end is real deep at 9 feet. For the first acid adjustment I will come clean and admit that I used 1 gallon...

Thanks again, That makes sense the acid demand is lower than it was last year.

Thanks chem geek. I am going to be adjusting chemistry (TA) for a SWG, when I close this autumn (Oct - May). Is there anything you can recommend to avoid this happening next year? Lower CH? Testing and adjusting Chemistry while pool is closed?

Update: Based upon browsing this forum: I tried dropping the sediment into MA and it fizzes, is this the acid test for calcium-something? I believe that this is a minor scaling issue so I dropped the PH to 7.2 yesterday and it appears that vigorus brushing helps to remove what is left of the...

Yes sorry I forgot to mention that. I took a look at that link and my deposits not as crystalline as those in that thread and definitely not as severe as those calcium sulfate deposits mentioned in the article.

Hi All and thanks for the replies. Sorry for the 9+ reading it was just a notation to myself to indicate what appeared to be an off the scale reading (above 8.2). I use the TF-100 test kit for my testing and the pool calculator to adjust chemistry. The 150oz of MA did bring the PH down to 7.5, I...

Hi All, We did a pool renovation last summer (August 2014), I closed the Pool on 9/20/14 with a PH of 7.2. The pool was opened yesterday and after opening yesterday and running the pump for 5 hours: I am currently using CL tabs and once this is resolved I will add the salt and convert over...

It is Diamond Brite Super Blue, the actual color or appearance at anyone moment depends on the sun and wave action.

Love cars, all kinds; when I'm not testing my pool water or skimming leaves you will probably find me washing the cars.

I have been following the TFP method since we did our renovation in July and I must say it is looking good! I was considering adding borax next season, but I don't want to blind anyone with more sparkle. Thank you Jason and everyone else that makes the forum so helpful.
