2nd Day of slamming

Merged by moderator, please keep related posts together to maintain continuity of story. Thanks, jblizzle

I did the oclt last evening and I lost 6ppm added what pool math told me to add to bring my number back to slam 31 waited about 4 hours and checked 27.5 added the 33 oz to bring me back to 31 waited 2 hrs with swg running also and test shows 27.5 added the 33 oz again will test in 1 hour this time?? this is frustrating could I have other problems it is 100 degrees here today

What is your CYA? I thought I saw you say it was 40ppm, which would make shock level only 16ppm ... or did you raise the CYA up to 80ppm?

 

[joeam]

it was 75 when I started the slam should I be checking it?

 

[jblizzle]

No. I just saw you list 40ppm ... then went back and saw you added more.

 

[joeam]

test results FC=30 CYA=60 so my cya has come down some is that normal??

 

[joeam]

should my cya have come down?

 

[jblizzle]

Not if you did not replace water. Maybe the lighting was different?

 

[joeam]

I did add some water duh I forgot that thanks for reminding me

 

[joeam]

only lost 1 ppm last night went ahead and slammed today to 24 now im going to let it come down to my normal level correct? When do I need to do a complete set of tests?

 

[jblizzle]

Any time. May as well wait till the FC is under 10 so the pH is valid.

 

[joeam]

well I went ahead and did another oclt last evening and it shows a loss of 1.5 ppm WTH hmmmm im not sure what to do now? FC was 14 last night 12.5 this morning I ran the swg for a hour and it returned to 14 all showing little to no CC where should I go from here?

Hi Joeam,

Remember, there are 3 things that must happen before you can stop your SLAM process:

1. Clear water

AND

2. CC < 0.5

AND

3. You pass the overnight loss test of 1 ppm or less of chlorine loss.

It sounds as if you have completed 2 of the 3 so you aren't done. Continue your slam until you pass them all. And make sure you turn the SWG off before performing the overnight loss test.

Well my oclt from previous night was a loss of 1ppm and I went ahead and slammed yesterday anyway and checked again overnight and loss shows 1.5 also it says run pump constantly until slam is complete and I am afraid this pump will burn up from running so long? should I just keep running it?

 

[joeam]

OCLT results 0.5 loss so I am good?

 

[JasonLion]

Should be good

I didn't see it mentioned but during a slam you should be brushing all the surfaces of the pool including the ladder at least once a day. Helps with water circulation and getting anything clinging to the liner or ladder out floating in the water where the chlorine can kill it and the filter can hopefully trap it.
Even though it sounds like your SLAM is done, brushing is still a good idea to help keep everything clean.

Also, take the time to read and possibly re-read Pool School so that you have an increased awareness of what's going on with your pool and how to manage it. I have skimmed articles that don't exactly apply to my situation and yet find later I am aware of it in case a problem comes up.
Keep a record of your test results, with a notation of what your own pools goal levels are. Your pool goal levels are based on type of pool, how you chlorinate, sun exposure, etc. This way you can see patterns of pool behavior and keep track of what you're doing that works and what doesn't.

 

[joeam]

Test results today and my actions FC=10. CC=0 PH=8.0 CYA=45 TA=110 I have added 30 oz of Stabilizer added 47 oz of muriatic acid.

Be careful treating your pH when your chlorine level is over 10. Being greater than 10 causes the pH test to be unreliable and you might end up overdosing the pool and once your chlorine level drops you find your pH far too low. Just be aware.
