When you say that pH, TA, and FAC are all in spec according to the strips, that doesn't really tell us anything because the strips just aren't that accurate. It sounds like you have iron in the water, which will need to be filtered out. You have a couple of options there....if you'll log out of the forum, go back to the forum home page, under the second set of threads, and look at the first one there that says "pool chemistry for Intex-type pools", then open that and read the first sticky, called "before you fill your Intex-type pool with well water!". That sticky should answer most of your questions, but if it doesn't, feel free to come back and post them here and we'll try to help.
