It's done as good as in any soft water tanks in my hard water. 
Does the same in Marin and down there as in the rock hard stuff.
You know what Steve does with it in GH/KH's of 5 ranges. It has
high light and high nutrients and it does well in low light
also. Mine looks 100% better than the stuff at Albany Aquarium.
It's hurting and very small. I like the small part but it is
stunted. Steve's looks much better at least today:)

Is 2 watts a gallon high light? Not in a 24 inch deep tank but
16 to 20 inches.

Just don't block the light. Jeff has grown it in a 10 gallon(1/2
20 gallon) with a 15 watt over it and it looked very nice. It
does look better in the high light tanks though. It's also more

Same as above. 2 watts a gallon. A simple 2x20 watt 20 gallon
tank will do super for both plants with CO2 and some decent
gravel set up. Balancing the lights to the nutrient load is the
key. It's hard when your use to 2 watts to jump to 4 watt a
gallon and the reverse also. Not an easy step for folks. I
slipped a few times on that one. Made assumptions then went back
and re evaluted things since I had to deal with my tap water
this time and could not just add or delete things. Basically I
would've been forced to do the whole RO routine and reconstitute
everything *or* deal with what the tap has in it. I gave it a
long observation then each time I moved from one place to the
other or worked on a tank in one area that's different than
It's easier to just NOT add things to test than to add things to
test. Few folks are willing to muck up their tanks to see if in
fact it's A or B that causes a problem or not. I am. I'
ll go along and test thing to see also. I have no problems in
soft, medium, hard or rock taps. I can grow the same plants in
the same manner in all the taps. I do not add some of "Tom's
soft water tonic":)If the plants are doing well in all the taps
is it the hardness? A few commonalities exist but hardness is
not one of them. High PO4 's, low NO3's, high K+, and high iron.
High numbers of algae eating critters. High CO2, decent current,
good access to light(pruning and water changes etc). No tricks
or M. Weiss BS.
