Before finding your site I was a Leslie's customer. I primarily used the for water testing outside my OTO but I did get pool stored!!
I just received my TF-100, have read for hours on your site and have figured out the basics. I am trying to install my SWG but have encountered a CH problem. I do have the speed stir and have read your extended directions.
Test results yesterday
Ch 650 !!!
After I took ph down to 7.4 today's reading...didn't retest TA
Also know my chlorine has to go up experimenting with 10% and pool math
Today ch 600 using the instruction to add the 5 drops of R0012 first
Once I found cya on high side I picked up liquid chlorine to help me until I can install the SWG.
Leslie's last ch test reading was 260 on 5/23. The ONLY chemical additions were Chlorbrite which I just stopped and Morton's pool salt.
We also completely cleaned our DE filter and added new DE.
I tested my current fill water at 175.
Here is the problem/question.... Could my Morton's pool salt be contaminated with calcium? I could add some of it to my fill water and test that theory.
Other theory is that Leslie's calcium tests are all bad !! I actually added some hardness up initially because my fill water is low. Maybe their tests are off and I added too much when I set up the pool.
I don't mind the cost of a partial drain but we are in a major water shortage/ drought here and I don't want pool popping/ problems. I am afraid to drain!!!
Would you keep adding salt, set up the swg anyway starting with a ch that high?
Will the regular use of stain and scale removers/ scale free, etc. help with scaling on the swg?
The pool is 7 months old and I had been using some scale free on it but I do have some calcium on the grout lines above the water line. Not bad but you can see it on the brown tile.
I have been watching my chemistry vigilantly, I've just been ignorant. This is my first pool.
