Just take a tap water sample to the LFS and have them test it for you IMO.
I have my own test kit that I test water with. However, I live across the country right now so I can't really test the water out there in Georgia, lol. Just figured maybe someone out there would know so I could think up some livestock ideas for the aquarium that will be started up out there in the future.
I've always had a bad habit of planning ahead and I guess this is one of those times that just isn't going to work out!
