My feelings are that unless you are trying to get fish to spawn, the ph level is unimportant. Most species of FW fish can thrive in a very wide ph range. It is the sudden shifts in ph which cause fish problems.
Also, the cheapy test kits where you add 3 drops to a small vial are both inaccurate and subjective. How large is a drop, and what color does it most closely compare to on the chart?
I recently tested 2 of my tanks with a color comparrison test kit. I couldn't tell if I were reading 6.6 or 6.8 so I assumed 6.7 on both tanks. I then tested the tanks with a newly calibrated MilwaukeePH600 pocket tester. I got 7.1 in one tank, and 7.2 in the other. What do you think?
