re: hard water plant
>>Define moderately hard............<<
I say this mostly from report--all the aquarists here
say the water is hard in Houston. One very reputable
guy laughed when I told him my GH was about 7-8. He
said my test kit must be old or something. And no I
haven't bought another kit. So someone besides me is
going have to say exactly what it is. (and no I don't
care to call the water municipality). So maybe the GH
is above 10?
>>Also, prove it is due to the hard water.........<<
Prove what? If your hypothesis says "plant x can only
grow in soft water" and I am growing it in hard water,
then the hypothesis needs tweaking.
>>Also, how many species have you kept over the years
I've been in the hobby for 2 1/2 years or so. So no
longer than that. On the other hand, I don't see how
this question is relevant. Either the plants have
grown or they haven't. "Generation time" for the
plants I grow is very short, and I have been through
multiple tens if not hundreds of replanted cuttings.
I can say this: I have never bought a plant twice.
And I have never bought large portions of plants.
I have Rotala wallichii and it has done well in what
would be called
moderately hard water(KH 5+ GH 9). P stellata so so.

I have had no problems with SAEs and wallichii
together. The only time I ever had a problem with
wallichii was when I wasn't doing adequate water
changes. And that was a long time ago. Grows like a

well be due to something
other than the GH/KH. They may be due to the gobs of

I add neither P nor N.

grows great until I do
a water change, then stunts. I have a full range of
test kits but just have
not gotten around to it yet.

I already reported what I believe to be the solution.
Add more iron. It keeps the leaves green. So far no
one has confirmed (seconded) this. Try it.
