So I have this liquid test kit (not sure of the brand) and it has the little test tubes and the little bottles of whatever those are and the little color charts. When you test your water, do you hold the tubes right against the card or an inch or so away from the card...the directions say hold it up to it (???). On the ammonia test and the nitrate test, it makes a BIG difference in the color when you hold it against the card or away from it a little.
Thanks!!!!
