How does my local water look?

Here's my local water report. My test kit measures over 300 ppm and my locality says the hardness can range from 19 to 28 grains per gallon and I think I'm in the 28 grain (478 ppm) area.

Can I grow stuff in 478 ppm hardness? I'd like to grow some minimoss, pigmy sword, hair grass, and other grasses to make a carpet on the bottom of the tank.

Is it going to be really tough to grow plants in this? I'm thinking about collecting rain water.

If I drive with a barrel to some family's house I can get 7.5 grains ( 129 ppm ) hardness water. Is 129 ppm a lot more suitable? Eventually I'd like to have Discus.

Hopefully it looks clear. Otherwise I would be suspect of it.

That's 17dGH or 27dGH (depending on which value you use); which is really hard. I'm not even sure if it's below safe standards?

I would either invest in an RO unit or if you live in the tropics then rain will do fine. Then again you live in Chicago, are you sure the water is free of sulfates? You can get an 6-stage RO unit for less than $150 if you're willing to spend. I mean with Discus, taking risks isn't much of an option.

Any time you're passing through Glen Ellyn, I'll sell you some good old Lake Michigan water at reasonable rates!
(Or I could toss a couple jugs in my trunk as I'm driving out to golf at St. Andy's!)
