UGH! How many times have we seen folks (myself included) chasing chemistry problems caused by bad test kits. Just because it is brand new, does not mean it's really "new". No telling how long it sat on a shelf.

Take your test kit and a water sample into your LFS. Have them test it AND you test it. If they aren't using Salifert or MAYBE Seachem kits, don't bother (I had a bad reagent from a Seachem kit a few years ago). I'm betting that you have a bad kit.

Look, I know that Salifert kits can cost as much as an "all in one" from some of the other. It's just that you can actually TRUST their test kits. Try fleabay for them, at a discount.
