do you have a thermometer on your tank? like one you stick on the glass? also, when you go and pick up the water conditioner ask the LFS if they'd test your water for you, some will some won't, but it saves you spending a ton of money on test kits. If they say yes, take a little sample in a sandwich bag to them and they can let you know where you're going wrong, and where you are in the cycling process.
