If you do ammonia dosing, make sure it doesn't have surfactants in it. If you shake the bottle, there should be NO bubbles. If there's bubbles, don't use it. Usually ACE hardware will have it, but none of my other hardware stores had the right kind. It's not that complicated, just put in a little bit at a time until you get up to 4ppm at least. Put a little in, let it mix and test. If not high enough, add little more and test again, etc. if you go over 4, that's fine- it'll just take a little longer to come down.
