Hi Laura,
This is David in Lawrenceville. I have the same type of water. Here in
Lawrenceville the reason is because what little stuff is in the water is
phosphates to reduce the leaching of lead out of the pipes! Makes ya thirsty
huh. I add some peat to the water, even a little bag of it in the filter
will help. Plus I add a very small amount of either yard lime or Seachem
Equilibium to give the water some buffering ability. Between the two I can
get the pH to stabilize around 6.6 - 6.8. Without it, the pH will go from 8
and crash down to below 5 with the nitrates killing the fish within a few
days in a crowded tank. CO2 will also help bring down the pH, but it still
needs some buffering ability.
Hope that helps.
