Perhaps it was I that was conributing to confusion. While testing the tank is important,so too is knowing what the tapwater's make up is. That way one knows what the effect of weekly water changes will have on the tanks chemistry. Many are those who report ph from tap at say 6.8 but yet their tank tests at 7.8 . First questions usually ask what type of substrtae and or rocks or decorations are in the tank. Others report tapwater with pH of say 7.8 but tank tests at 6.8 again,, questions such as what type of decor is present, driftwood, Is peat used in filtration?, CO2 injection?
My goal is to make folks aware that water used for water changes should be consistent with respect to it's make up and that in the tank . Otherwise with each water change, fish will stuggle to adjust. Some more than others.
