Ok- new pool to us. 23k gallon SWG gunite pool. Here are my first test results:

pH 8.2
Free Chlorine 0.5 (or 0) it was basically clear)

CYA 30ppm (or again basically 0 as I got the water all the way to the top of the viewing tube and could still clearly see the black dot)
IMG_0972.jpeg IMG_0970.jpeg

Total alkalinity 140ppm
Calcium hardness 375ppm
Salt 3800 ppm

According to our SWG the salt level should be between 2800-3400.


What is going on here? There is basically no chlorine in this pool. Is our SWG even working? I increased out SWG % from 50% running 8 hours a day to 100% running 8 hours/ day. In the meantime should I go buy liquid chlorine to add to the pool? How much should I add?
My feeling is that our SWG may not even be working at all.

Thank you for the help!
 
Download pool math and configure your pool. Enter your results above, your CYA is 0...Link-->PoolMath

Get some liquid chlorine, some muriatic acid and some dry chlorine stabilizer.

Add 30ppm of CYA. Use the sock method. Use pool math to calculate the amount.

When the CYA is in the sock in the pool, add 5ppm of liquid chlorine. Use pool math.

Wait 10 minutes, then,

Lower your pH to about 7.6. Reduce pH in .4 increments, test after 30 minutes. If still not to 7.6, reduce again the needed amount. Use pool math. Use muriatic acid to lower pH.

Let's worry about the SWG after we get some chlorine in the pool.

^^Do this, then do this test tonight to determine if algae has started, even if you cannot see it....Link-->Overnight Chlorine Loss Test

After you have done everything but the OCLT, fill out your signature...make sure you include all the information about your SWCG.

Thank you for the quick reply!
Working on signature now.
Are you saying add to 30ppm? The pool math app has my “safe range” between 60-90ppm.
Going from 0-30 on the pool math app would have me adding 5lbs cya.
 
Add 30 for now. If you have algae and we need to clear it, it will take more chlorine at 60. Almost impossible to clear at 70-90, and you likely would have to drain water. Add 30 until we get everything clear and working.
Should be 5lbs 11oz or so, no?

Great job so far...
