    New SLAM question

    I have been SLAMing my pool for a couple of weeks. Last weekend, we passed all three of the tests (FC overnight drop, CC = 0.5, clear water). I added some CYA Saturday as we had almost none (targeted ~40) and will test in a couple of days to see what we have. I have been keeping an eye on FC levels to see how it will react and how much I need to keep in it at night to make sure we don't drop below the minimum (I am using ~5 ppm based on 40 CYA as my targeted min until I know for sure on the CYA number).

    After using the pool today, I notice that the water is a little cloudier than when we started. Would you suggest I keep the pump running tonight still to clear that back up?

    Also, should I go ahead and bring down my pH at this point?

    Full test results from today.

    pH - 7.8
    FC - 12.5
    CC - maybe 0.5 (it might have had a slight pink tint before adding 1 drop)
    TA - 90
    CH - 110

    Thanks so much for all your help. You all are much better that that pool shop.

    I would let the pump run overnight and keep the FC up for a day or two.

    Wait till you drop your FC to maintaince levels to adjust your PH. High FC levels skew the PH test.
