Honestly...I'd at least try to use your properly ph'd tapwater. Just let it sit-out uncovered overnight, which dissipates the chlorine. I use pretty hard wellwater myself, (260 to 300 mg/L) and have no ill effects. Used it for my coral tanks, too, but admittedly used it half-n-half with R/O water. Worth the effort to at least find out the plants reaction to it. Could save shitloads of effort and money.
