    Closing question

    Hi-
    I have been BBB all summer. I have been able to use liquid, sometimes lithium, and some pucks. I did put a nature2 in at opening but am using the chlorine/cya ratio not what the nature2 recommends. My ph has not changed much (7.5-7.6) this whole summer never having to add anything for it!
    TA is around 225(high in fill water). never much luck bringing down so haven't tried this year
    CH 250
    cya 60
    fc 10
    use tp-100
    i went to the pool store to sign up for the blow out to close. was given the sheet to follow for adding closing chemicals.

    Scale inhibitor
    Banish
    Natural Result and pool tonic

    Been reading up on these and here realizing not needed but wondered since i had put the nature 2 in does that change additions to close?

    Thanks

    The Nature 2 should not change the closing recommendations you find in Pool School ... although why are you continuing to add metal to your pool anyway?

    "pool tonic" ... really?!?! ... I can just picture the guy on the corner "Git ur pool tonic here ... greatest chemical known to man ... you would be a fool to be without ur pool tonic!!!!"

    Re: Closing question

    Skip all three pool store suggestions, since you do not need more copper in your pool (Banish), your pool is vinyl and relatively low in CH (Scale inhibitor), and who knows what junk is in the "Natural Result and pool tonic" .

    Here is the pool school article on closing a igp, only chlorine and polyquat60 algaecide are recommended: http://www.troublefreepool.com/pool-...in_ground_pool

The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.

    Thanks!
    The nature2 was put in before i understood its "purpose" !
    It used to be suggested to use algae all 60, not sure why they changed to Banish suggestion.

    You can use whatever you want ... we can't stop you ... we just may not recommend it and it may not be as effective

    That appears to be
    Alkyl dimethylbenzylammonium chloride
    from this msds.

    There is a thread on that type of algaecide here: http://www.troublefreepool.com/polyq...de-t18101.html
