i'm in the burbs, west of the city, but i used to live in Upper Darby - i get the same city water as you probably though, but mine comes out of the faucet at 7.2 - 7.6 PH....is your PH 8.4 in your TANK or fro the faucet? You can use bags of peat moss, driftwood or almond leaves to soften water and lower PH, and you can used crushed coral and sea shells to raise it a little at a time, but like i said it gets to be a PITA.
Cool! It gets to 8.4 after it's gassed off overnight (and is 8.4 in the tank as well of course). But my nitrates are literally 40-80ppm from the faucet which just seems crazy to me (0ppm from my RO water so I know it's not my test kit). Then again I'm a newbie so who knows! In any case, it's definitely a PITA hahaha.
It's easier for you if you plan your tank/fish around the type of water you have instead of using buffers and all that other nonsense - it just gets too annoyingly pain-staking and tedious. It usually doesn't end well for people who want to keep soft-water/blackwater species around here unless you spend a fortune.
Definitely don't want to spend a fortune but it looks like I'm heading there anyway

You should try Captain Nemo's/Natural Pet on DeKalb St. in Norristown/West Norriton or Fins, Feathers, Paws, and Claws on Rt 63 in Harleysville. Both store owners are friends of mine and are very knowledgeable and experienced...i even worked at Nemo's for awhile.
And therein lies my problem. I don't have a car (and very, very rarely have access to one) so my LFS access is limited to wherever a ZipCar can get me for a reasonable price
