    Vacation

    So I am gong away for a week. I have an intex 15*48 pool. I normally use bleach. I have old 3 inch chlorine tabs. They are not tri-chlor. I am wondering if I can hang them in the pool near the inlet and if so how many should I hang for a week. Also any other suggestions??? I think I will take the filter out and just run the pump.
    1) The size of your pool in gallons 4440.
    2) The type filter you have is an Intex 2500 gph and it has a re-useable fabric filter
    3) If your pool is an AG (above ground)
    4) Intex 15 by 48 metal frame.
    5) If you know, tell us the size pump 2500gph and the size (flow rate) of your filter.

    Most all of those pucks are, in fact, tri-chlor.

    Your CYA level determines how savvy it is to use pucks....can you tell us your CYA?

    Those Cal Hypo tabs will dissolve very quickly in your pool and make a mushy mess....I wouldn't use them except to put them in the skimmer. pump running, one at a time.

    With a CYA of 40, you can use tri-chlor tabs but not much more than a week......your CYA will get too high

    Re: Vacation

    Those are Cal-Hypo pucks so they will not add any CYA to the water but they will increase CH. For every 10 ppm Free Chlorine (FC) added by Cal-Hypo, it will also increase Calcium Hardness (CH) by at least 7 ppm.

    So the relevant number to know is your current CH level. Since you have a vinyl liner pool, your CH is probably low unless your fill water is very hard. So if your CH isn't high, you could use those tablets for chlorination. Normally they are used in specially designed inline chlorinators (different from the ones that are used with Trichlor), but it sounds like these are OK to use in the skimmer. Since Cal-Hypo raises pH and doesn't lower it, using them in the skimmer is probably OK, at least while the pump is running. [EDIT] one at a time as Dave said, to be safe, since they do tend to fall apart. [END-EDIT]

    [EDIT] Also note that according to the HTH® website the product also contains chemicals that "Inhibits scale" and "Contains skin softener" which are extras that you don't need. [END-EDIT]

    Epsom salt. That's the super-secret "skin softener" that these things contain. It makes up over half of the "other ingredients" in these things.

    Epsom salt is magnesium sulfate so is no problem as far as the magnesium is concerned and the sulfate would only be an issue if it got high (300 ppm or more) in a plaster pool.
