I just got my tank up and running a few weeks ago after a 5 week fishless cycle.

Went OK just one minor ph crash near the end.
This 55 gallon tank is now the home of 3 fantail goldfish and 5 small cories all of which seem happy, active, and eat well. I have changed at least 20 gallons at weekly pwc's and all seems well except I'm having trouble keeping my ph stable.
The tap water comes out at around ph 7.5. A few days after a water change I can test the tank water at 6.6-6.8. I went and got an API GH /KH liquid test kit and my water measures GH 5 and KH 2.
Today for the first time since the cycle I had a nitrite reading over zero, it's 0.5ppm, does the low ph adversely affect the BB?
So what should I do? Crushed coral? Baking soda?
