    first year with SWG, how far from rec before take action?

    First year with SWG, after a year when I didnt even open the pool bc frustrated with local pool store and their informationless "just trust me" attitude. So took the time to learn the chemistry THaNK YoU TO THIS fORUM, and Amazingly, I have the pool pretty close to perfect but just want to know when I should take action if the change needed is small. The pool is crystal clear and has been for three weeks. Alkilinity initially a problem at 280, but followed the awesome guide, (acid to decrease alk/pH then increase pH with aeration (test,repeat repeatedly)) and have things in hand I think.
    Here is where I am:

    FC 3
    pH 7.4
    Alk 100
    CYA 58
    Cal 180
    Salt 3500

    To tweak, or not to tweak. That is the question.

    To improve on that would be mostly nit-picky and not worth doing. Very nice work....enjoy your pool!

    Great job My only suggestion is to target FC of 4

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    thanks! hot day today in the Bluegrass state, so prob need to turn up the chlorination settings a tad this evening. it has been sitting at 5 until today. Related question: with these numbers, do I need to shock sometime? no visible algae growth and pool doesnt have that "slick" floor feel you sometimes get if algae is starting. I read somewhere here that shocking is really only in reaction to a condition if chemistry otherwise OK

    do I need to shock sometime?
    No. If you keep your FC at adequate levels (3-5ppm) you probably will not shock the pool all summer.

    Welcome to TFP.

    Well, while we're nit-picking

    I'd bump the CYA up to about 70 and then you should hold just a bit more FC at the same setting and that'll make BF happy. And we all want to keep BF happy
