    So I've been running a DSM 48 gal as I'm sure a few of you have heard before. One of the plants I'm trying out is Elatine triandra. I've got some from the same source both emersed and submerged.

    The emersed form actually loses almost all of its plant mass in the case of my setup. Everything melts except for some small axillary buds that put off vegetative growth. From there, I'm getting small plantlets that survive the emersion and have begun to root.

    Apparently these same shoots are responsible for their reproductive growth as well, rather than being strictly off the terminal shoots:
    Elatine triandra - mudwort or three-stamen waterwort

    Elatine Triandra

    Hi Philosophos,

    I am assuming DSM means Dry Start Method.

    I have also noticed that E triandra does not like 79F (26C) or above underwater, I have not noticed a problem in the above water ones. Just read http://www.aquaticplantcentral.com/forumapc/plantfinder/details.php?id=202 they don’t like over 76F (24C).

    Propagating Elatine Triandra : Greg Watson's Aquatic Plant News
    Elatine triandra Schkuhr - Encyclopedia of Life
    Elatine triandra Schkuhr: UW Stevens Point Freckmann Herbarium: Taxon links
    Long Stem Waterwort, Elatine triandra

    I cannot say I have seen this, I use very rich substrate, and I have read and found Elatine triandra likes and needs rich substrate and really likes iron.

    The only thing I can think is you are cutting the nutrients too close, you and your fancy arithmetic, you know how you are, well, smart. :p

    I have a couple of trays of E triandra and a ‘lakes edge’ tank where it grows right up out of the water and covers the ‘shore’ and ‘hillside’. ;)

    The only ‘melt’ I have experienced is when the growth gets thick and starts rotting underneath; on occasion the rot has lead to plantlets floating off. When light is blocked as in when a lotus or arrowhead grows leaves out over, the plants get stringy and a bit yellowish.

    Hope that helps but probably not. :eek:

    I must've missed your post last night; the front page was on overflow.

    I haven't found elatine demands cool temperatures either. I've got some submersed already in another tank that gets into higher temps and it looks great for how long it's been in there. Temp has been around 28c and no complaints.

    High nutrients in both the substrate and column are somewhat of a default for me these days; I like to be able to have a lot of freedom with my plants between the tanks. Aquasoil and EI liquid dosing all around.

    Going from emersed to submersed sounds like a good idea; I've wanted to do it for a long time, but I've never really chased the concept of doing a terrarium that much. How did it turn out?

    The melt sounds like what happens with both HC and glosso when they get too intense.

    As for what's up... car troubles mostly. I stopped by a relatively new LFS but it turned out to be all SW. Very nice fish, but not my thing right now. How about you?
