I took two samples:
The first, what I will call the warm sample, is water from my kitchen tap
that is mixed, hot and cold to match the aquarium temperature. This is what
I use to do water changes. The second sample is cold tap water.
Thanks for your help, I'll retest the pH again tomorrow and post the
