    Do I need to SLAM?

    New pool- see specs under signature.
    FC 2 CC 0.8 Ph 7.5 Hardness 173 (but just added more) CYA 34 (more is currently in sock in skimmer) pool is SWG

    So pool is crystal clear and I suspect within the next 2 weeks I'll have hardness and CYA where they need to be.
    Is the CC above 0.5 enough reason to SLAM the pool?
    If so, I am confused about the CYA/chlorine chart on this website:
    Under SWG for a CYA of 60 there is an asterisk that states 'not recommended', yet the CYA of 70 and 80 do not have one.
    Is that to mean that I need to get the CYA up to 70 or 80 before I start the SLAM? I thought I read that ideally it should be done when CYA is around 30, but the chart for SWG starts at 60...
    Can someone please explain?
    And again, based on above do I even need to SLAM right now?
    Thanks again for all of your help.

    The chart is saying that in normal pool operations with a SWG we recommend 70-80 CYA, not that you need to get to that level to SLAM.

    While talking about the SLAM you have clear water & 0.5CC. I would just conduct and OCLT and if you pass call it a day and go,swimming - no need to SLAM. If you fail the OCLT then you should SLAM, but I assume it will go quickly.
