> 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.
Interesting. I guess it's just a case of too many variables from one
tank to another. Experimentation may be the only answer. In my case
the water was out of an aquifer which flows through farm country. I
know the ph varies from 7 to almost 8 throughout the year. I suspect
there may be some farm chemicals in there that I can't test for.
