No worries H...

Parameters: 0-0-10 with ph 7.5 - gh 7.5 - kh 6
I don't use CO2 but do use liquid ferts, having started with TNC Complete, switching to Lite but then switching back to Complete...
Substrate is "Walstad Method" style: John Innes #3 capped with pea gravel (
aside from an area of sand only)
In my experience, it's much slower growing than the Elodia pond weed and the Sessiflora and I personally would say that it's nearer medium speed, or has been in my set up... Those Amano shrimp have nibbled fairly significantly on the younger leaves, usually victimising one leaf at a time until it has completely gone... Obviously not damaging the plant to the point of killing it though, plus they tend to leave it more alone since I switched to full size algae wafers (
from the micro sized ones)...
The only trimming I've done so far is of a few stalks where the leaves were completely eaten... So again, in my experience I would definitely describe it as an easy plant - however there is one caveat which you may have picked up on in the Tropica link... It is a plant that needs a lot of nutrition for the most vigorous growth and my TNC dosing is a fraction of the recommended amount and probably why, combined with the Amano shrimp, it appears to grow at a fairly modest rate...
On a more personal note, there's something about that plant that I really like... It has a delicate character, even though the leaves look so large - if you look at the stem thickness you'll see they're quite thin really... If you were to ask my opinion, I'd say "go for it"...
Last point that may or may not be significant, but mine was from a tissue culture pot...
