We got the filter & pump combo. We bought & assembled it about 2 weeks ago with sand bought at the same pool store. I have not yet taken it apart to check the sand due to nasty thunderstorms in our area this afternoon. I did just come in from cleaning leaves from the pool and the emptying the skimmer. I went ahead & checked the water with an HTH test strip (as that's all I have at the moment). I could smell chlorine in the water as I pushed it around, but here are the results:

TH: 200
FC: 0 to maybe 1. The top of the square was 0. The bottom of the square was around 1.
pH: 7.2
TA: 120
CYA: 30-50

There is still quite a lot of settlement on the bottom of the pool. I will try to post a picture if it makes any difference.
