I put a trichlor puck on the stains, and it definately lightened them. So I guess based on the other thread, my next steps are to get the water back in shape, and raise the chlorine to 30ppm? Should I proceed to get my water back in shape in all aspects CYA, pH, Alk, etc. and then raise the chlorine, or should I just go about raising Chlorine? I've ordered Ben's Test kit to get me started in proper water chemistry.

I guess the advice, "just get some test strips and just watch your pH once in a while and keep the chlorine just high enough so it doesn't turn green", I recieved from others wasn't quite enough.
