30GH~best options?

I've got a few ideas and I'm sure most should be eliminated, so here goes:

I'm trying to get my GH down around 6, I'm setting up a CO2 injected 100 gal tank, still not sure what biotope, although I'm seriously considering Travis' African Mbuna setup since my water is already so hard. I've got a small 10GPD RO that I could tap into for weekly changes but was hoping I could cut my GH down by using water from our in-home water softener (one of those Sears Resin-bed softeners that use the salt pellets). It would be much easier if I could go this route (and cheaper too w/ a lot less waste water) and it would retain my KH around 6. Just wanted to know if this is possible or if the water from the softener contains other by-products that will harm the plants & fish.

water softened water tends to be high in sodium content. I think you can switch the type of softener salt you use to potassium chloride. That'd work, but the alternate salt might offset the cost of using that over RO water.

Thanks for the tip Malkore, I'll check into the other salt as it would really simplify things, do you know if there are any ill-effects from the potassium chloride?

Just came across this thread. My GH ranges anywhere from 14-19 dGH and most plants do quite well. There is an initial acclimatization period where some plants get a bit shocked but even Rotala macrandra is doing quite well in my tank now at 13 dKH and 18 dGH

The computer allows you to make mistakes faster than any other invention, with the possible exception of handguns and tequila.

Don't know if this pertains or not but. I am a plumber and I install water softeners for homes sometimes. We are told to tie the hose bibbs in before the water softener because the softened water will kill the customers plants when the water.
Don't know for sure just thought I would share.
