    Talking Opening, do I really need to SLAM?

    Finally tested my levels after dealing with a leaky filter. It's been very cold, but my water looks pretty clear. There is some debris on the bottom which I'm going to get up tomorrow.

    My numbers are:
    FC: 0
    CC: oops, didn't test, assumed 0 since FC was 0.
    TC: N/A due to above
    CH: 75
    TA: 50
    CYA: 30
    OTO: 0
    pH: 7.0

    Any recommendations on first steps? Since my water looks pretty clear, do I need to SLAM?

    Thanks for all your help!

    Why would you not SLAM to ensure there is nothing in the water?

    If there is not much going in the water, then you would pass the 3 criteria very quickly.

    If you don't see any algae, you shouldn't have to follow SLAM process. I would get that PH up. Use pool math and either washing soda or borax.


    Edit

    Jblizzle is right. I think we were typing at the same time. There is no harm in elevating FC upon opening just to be sure.

    And if you are going to do that, may as well do it at shock level

    Might be that the "SLAM" only lasts 1 night and you are done.

    Cool, sounds good, I'll SLAM first, then maybe toss in a little baking soda to bring up my TA and hopefully my pH a bit.

    Do you think baking soda or soda ash would be better for my TA & pH levels?

    After those are good, I'll maybe toss a floater in to bring the CYA up a bit, then I'm in maintenance mode!

    What do you pro.s think?
