    Ben always said that pools find a value that they 'like', and you're best bet is to learn what your pool likes and manage around that.
    160 ain't too bad.

    Ok, these were my numbers from this morning using the HTH 6-way test kit from WalMart:

    TC - 4
    PH - 7.4
    ALK - 140 (it actually came down 20 more and now I'm DONE with it! LOL)
    TH - didn't work

    I know we have hard water (from a well, and no softener). When I filled pool water to the appropriate line and added 5 drops of hardness indicator, the water turned a light yellowish/tan instead of red like it said. Then I was supposed to add the titrant drop by drop until the "red" water turned blue. I kept adding (just to see what color my yellow would turn) and nothing changed. If anything it looked a little more clear colored. Does this mean my hardness is waaaaaaaaaaaaay up there, or that my chemicals need replaced maybe? I bought the kit last year in July. Not sure how long they are "good" for. Any ideas? Last year my hardness was 480 (yikes) but we have a vinyl pool and no problems with cloudy water so I didn't mess with it.
