SLAM - Shock Level And Maintain
CC level is above 0.5, and the free chlorine (FC) level is zero, started to SLAM the pool.
You need to have a FAS-DPD chlorine test
You also need to know your current CYA level 60 ish, and then look up the corresponding FC shock level.
USING bleach or liquid chlorine when SLAMing.
Check and adjust the PH to between 7.2 and 7.5.
Run the pump 24/7 until you are done SLAMing running on recirculate* should I run filter?
Measure the FC level= ** 0.1
Add enough chlorine to bring FC up to shock level ** up to 25
Repeat steps 1 and 2 as frequently as practical, but not more than once per hour, and not less than twice a day, until:
CC is 0.5 or lower;** waiting on fas/dpd reading
You pass an OCLT (ie overnight FC loss test shows a loss of 1.0 ppm or less); **I not sure if i was supposed to test this morning with the fas/dpd?
And the water is clear.** water has always been clear
Chlorine additions should be frequent, especially at the beginning. Algae and other organic debris will consume chlorine very rapidly at first. As things progress, you will lose less chlorine each cycle and can add more less frequently.
***So last night I added enough to get to 25 FC which is my shock level for my current level of CYA. I did not add more yet... How long do I keep it at shock level? Should I have my SWG running? Should my SWG be off during SLAM? My PH was at 7.3 when I started.
When do I test with the fas/dpd test and how high should FC be?( always at shock level?)
Brush the entire pool once a day** will do
Backwash or clean the filter as needed** will do
