    Also maybe it will be interesting to someone.

    I have made two pots one filled with 3:2 mix of perlite:vermiculite another 1:1 APS:Silica sand. APS is the same Butch used here, it did give off cloud of dust/vapor when first wet too!
    All components were rinsed and runoff water inspected while rinsing (levels were ~5ppm for vermiculite, ~3ppm APS, 0-1ppm for sand and perlite)

    Pots (4") were filled with mixes and washed again. So they stood like that slightly wet for two days. Today I flushed them and checked the runoff water (50mL each).
    APS:Sand - 76ppm,
    3Perlite:2vermiculite - 30ppm
    My pot filled with pure perlite shows 5ppm. So it is coming from vermiculite and APS. Also APS pot gives off some sort of a metal oxide smell.
    These were supposed to be media for pings

    Are Heli's tolerant to such concentrations of minerals in the soil?

    @jeff: yes, sandstone and sand are definitely found on the tepuis...however, more likely than not, heliamphora do not grow on these stones directly since water more likely washes them away...however, they are able to establish themselves on lithophytic organisms such as lichen, moss, and various grasses. these plant islands function very similar to that of coral reefs, where plants try to compete for available space, and even try growing on top of each other in order to do so.

    Most definitely, in fact i would be confident in saying they are not only tolerant, they thrive on it.... In addition, I root feed mine monthly. The only group that I have come across that really seemed to object to root feedings is Drosera.

    Personally, I think the 0.00TDS goal is way overstated and probably very rarely (if ever) found in nature.....

    Just my humble opinion though....... ummmm maybe

    Even well rinsed APS seems to leave a white crystalline residue.

    And, yes, Perlite is porous with open cells and closed cells in the nucleus. That's why Pyro cautions that it can act as a desiccant and should be avoided with tuberous Drosera :
    http://www.perlite.it/en/what_s_Perlite.asp
    The structure of the particles, clearly visible in some pictures (Pictures 2-5) collected with a scanning electron mycroscope (SEM), is characterized by open pores (small channels that form a thick network) and close pores (isolated cells and holes). The contemporary presence of those cheracteristics gives the rock an extremely high transpiring power (thanks to the open pores) and at the same time high impermeability to water inside the nucleus of the particle (due to the close pores).

    The problem with Perlite is it can be 91-98% pores which is why it is so light.

    HeliLover,
    Try looking up "Turface MVP" for your area here:
    http://www.turface.com/distributors/state/

    Turface MVP is a close equivalent for APS.

    There are some acceptable substitutes out there.
    Good Luck.
    Experience is the best teacher. At least it used to be.
    But then, common sense isn't so common anymore, is it.
