Once you start the
SLAM Process just test FC and CC and occasionally CYA.
Do not try and adjust pH or CYA when your FC is over 10. Your pH test can be invalid.
At CYA 40 your SLAM Fc is 16. Test often and bring it back up to 16.
thanks! I was just going to ask about adding acid. I will wait. Here’s the recent logs for today of what I did. My FC is now 17.5 Do I run the pump another 4 hours to both? Or all night? It’s run about 8+ hours today so far (2 four hour cycles) I will do an Over night Corine test and see where I’m at in the AM right? I can stop if it stays within 1 point correct? If there is no change in the AM do I add more acid?
