Not to be a jerk but...... Sometimes I do things out of curiosity that others feel is a necessity. Some people are more stringent on things like water tests, others like yourself, don't do them as often or at all. True to properly care for fish, some level of science is involved. Especially when trying to alter things like PH you can really hurt your fish if your not careful. That some people go to the extreme, and others are more relaxed is just part of any hobby. We need to remember we are all here to have fun and to learn. There is much room for misinterpretation on the internet, so let's all try to get along. I'm glad you found an answer, but as you said, now you are looking for that test kit anyways
