swg question for today

[mojopool]

ok, after mixing salt and stabilizer for 24hrs and running my swg for 3hrs this is my test reading
cl-2
ta=160
fc-3.5
cc-0
cya-70
ph-8.2

my question is, since I have just started it up, should I keep running my swg system to get the fc up? or do I try to get the ph down as a priority?

Both. Your TA is high and will come down when you knock that pH down. Knock it down to 7.2 and your SWG will aerate it back up anyway. The aeration will not make your TA go back up.

If I am reading your results, you have 2 ppm of CC, which means get the pH in line and then go through the slam process. The SWG should be off during the process, as you will not be able to do an OCLT with it continuously generating chlorine.

I have 0-cc and it reads 2-cl my ph is high and my ta is high. My fc is low. Which do I correct first? If I keep running my swg will my fc come up?

Drop the pH to 7.2. After 30 minutes, raise th fc with liquid chlorine. Keep the pH in the 7.2 to 7.4 range by adding acid as needed.

ok, thank-you, I will try that, should I keep my swg system going or just use the pump?

Run it all!

thank you....

having a hard time getting TA lowered....PH is 7.2

Read the instructions in Pool School, in the How To section, on lowering TA.

When the PH comes down to 7.0 or 7.2 it is time to start aerating the water. That will bring the PH up and eventually allow you to add more acid.

Lowering TA is a fairly slow, on going, process.
