Kem Tek 338 vs Jack's Magic Purple Stuff in salt pool?

[JimK]

Ben, when I checked the bucket this evening the water was still cloudy from the addition of washing soda. When first I started the test and added the chlorine, the water got cloudy, but cleared the next day (I didn't see any staining or sediments). When I then added the washing soda, it got cloudy again, but this time it has not cleared after more than 24hrs so I cannot see if there are any stains or sediments.

Any suggestions on how to proceed?

Do you have a K-2006 or an HTH 6-way drops kit? If so, what are your calcium and alkalinity levels?

Calcium is about 240, TA is 90-100

Hi Ben.

I let the bucket sit another 24 hours and now the water is clear. The only thing I see is white sediment on the bottom of the bucket. What do these results mean? Anything useful?

BTW, a clarification/correction; the calcium level I mentioned above is actually the "Total Hardness" per pool store testing. The TA figure is from my own testing using a Taylor kit (the figure is unadjusted for CYA which is 80 per my own test using Taylor kit). Today I purchased the Taylor reagents needed to test for calcium, but need help with that (see my post in the appropriate section).
