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.
