K-2006 kit ordered (used the amazon link from the forum). I have also started the bucket test.

Initial results -
Well Water is clear with slight blue tint
Pool Water is slightly murky with yellow tint

After adding bleach and waiting 15 minutes I saw no noticeable change in color or clarity.

I then added the Borax and will check them again in 24 hours.

The other thing that is happening is that I have now changed the filter twice in a few days and both times the water in the filter chamber was quite brown and the filters themselves had picked up quite a bit of brown material, so there is clearly some minerals or something in the water. My SWCG system is 6 or 7 years old now...is it possible that there is corrosion inside the system and is the source of the minerals? The pool water was fine until I first turned the system on (both pump and chlorinator).
