I do not have any problem growing it now<g>! I have a ton of it. Super
plant....yada yada yada.
I needed a well cycled tank. This was my problem, tank out of balance. My
filter pump was clogged up so there was very little filtration. Other plants
were not as sensitive. Give it good balanced conditions and it's a good
plant. It has since done amazing things and is an excellent bushy little
plant with many uses.
The plant does like CO2,iron, light,and well balanced tank. This I can
assure everyone. I think it does need some elements and can do poorly if
these are not there. Which ones? I'm not sure. Good general conditions have
solved every issue I've had so far.......
I use Flourite with some jobes and this seems to really make most every
plant around grow well.
The plant grew extremely well under Quartz lighting(MR-16 bulbs 12v DC) as
do well......all plants.
The plant responds very well to pruning. I have two bunches being tested
with a nutrient poor substrate(sand only using a RFUG) and a semi rich
one(flourite and jobes every so often) with no current through the substrate
and extremely high lighting on both tanks(110 watts on a standard twenty
gallon!). Basically, I got other nutty test and notions going on and at
these light levels thing crash fast unless your on top of it. This is why
I'm trying some things on the substrate as well. I can't keep up on dosing
the water column without testing daily (and even then all the levels of
nutrients?) so I'm trying to rely more on the substrate as a nutrient source
even if I have a nice old mature tank when tanks are at 5 watts/gallon ++
and only 16 inch depths. Things happen much faster.
I'll let folks know about my findings. Shouldn't take too long. I know what
I'm looking for and know what the bad signs are. I think I'm on to something
that will work very well and is simple and very repeatable in a variety of
Patience and maintenance is all I needed to well with it. I got a little
impatient and came whining instead of taking my own advice :) ,it happens!
