Depending upon the accuracy of the strips, the buffering capacity is low. But this would explain the tap pH of 7.4 becoming 6.0 to 6.4 in the aquarium.

Monitor this at a water change to see what effect; you can expect the fresh higher-pH water to raise the tank a bit, but we don't want it too great. A rise of up to .5 is OK, I have that. Perhaps change 1/3 of the tank rather than 1/2 and it should be OK.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
