Larry, I have grown java fern as well as the others I named in so many different tank situations over the yrs it would take me an entire day to list all of those details, and yes, that includes hard water. My tap water now is pH of 8.5 - 8.7 right out of the tap and I have grown, (and for some am still growing) all of the plants I listed in this water here without issues, without extras such as specialized substrates, fertilizers, CO2, etc. The only plants I've had issues with in the hard water (used to grow great in big city water with pH of 7.6) are the vals, the sagitarias, and amazon swords, though I think it is the high iron content of my water that caused those plants to dwindle, not the hardness.

I haven't kept track of Connie's daily missives so I don't know what
kind of water she has. But I have hard water, slightly alkaline, and
java fern struggles in my tanks - as do several others that like soft
acidic water.
It would be nice if, when folks said that a plant did great for them,
that they would specify the tank conditions.
BTW, if Connie, or anyone else, does have hard alkaline water, I've had
good luck with contortion val, crypt petchii, and most sword plants.
