Watermom, captured my initial reaction to your post exactly: "Yikes, another one!"

If you haven't started filling, let's try to do this right, and get you a testkit AND a plan BEFORE you start filling. If at all possible, purchase a Taylor 2006 or 2006C kit. If you like, you can order one through the Amazon link in my signature. (If the seller is not "Amato Ind", wait a day -- some of the other sellers are mixing kits up.)
