Don't do any water changes until then. If it gets stinky, run carbon in the tank. Just make sure you have a heater and good flow in there.
I agree 100%, but why dump the water if it reads good? I understand he may be missing a few ppm
in alkalinity, calcium, magnesium... But isn't it cheaper to put in a cap of supplements?
