So I started using filtered water from my local grocery store. I tested the water at good levels
0 ppm Ammonia
0 ppm Nitrite
0 ppm Nitrate
However after getting the tank setup and letting it sit over night I tested again and the pH was in the 8.0 High Range pH level. I am worried about this but not sure what I should do. I changed the water again a few days later and I got a slightly less reading of 7.4 High Range pH. Would buying a bottle of pH down help or should I just try a few more water changes to see if it levels out.
