    Most of these numbers make little sense to me. Rubrarubra, 120 PPM is pushing it.

    Question

    Hi Schloaty,

    If all your mineral numbers are less than 1% that sounds like extremely soft water to me. I'd take some to a local aquarium store or buy a pH, GH and KH water test kit there and see what you get. I'd hate to steer you wrong and city water chemistry can vary from day to day and season to season.

    Those numbers don't seem right or at least how they expressed them.. .9ppm is better than an RO unit.. which is highly unlikely. I agree to bring a sample to either a quality pet store or pool place and have them test it for TDS (total dissolved solids) the measurement should be in PPM or EC

    Is that a Nepenthes in your pocket or you just happy to see me?

    Yes Tamlin I know I shouldn't, but it works for most things and I hate having to constantly restock on distilled water. I might make a mini wetland/greywater system sometime to filter chemicals out of tap water. My aquatic utrics thrive in a pond that is filled with sun-treated tap water.

    Tony, that's what I thought. Sounded extremely low. But that's what the report says...AND the guy at the water dept. in town. The measurements are actually in mg/L, and they say 1 mg/L = 1 ppm. Don't know if they're telling the truth..

    We do have well water, does that make a difference?

    Well, I have a few common plants that I have doubles (and tripples, etc.) of, I guess I can use them as guinea pigs, eh?

    Shloaty,
    mg = milligram
    A liter of water weighs 1 kg.
    1 kg. = 1000 grams
    1 gram = 1000 miligrams
    so 1 mg/liter = 1 ppm

    I hope this isn't too confusing...

    Rubrarubra,

    I did the experiment for 2 seasons, and my plants did ok outside, but there the rains would leach out any accumulated salts. I grew S. purpurea and some D. rotundifolia like this for 2 seasons. Inside it's a different story, but if you are dedicated in occasionally top watering with rain or distilled, it might be ok. Another good strategy would be to repot annually.

    Update:
    Found something interesting....I measured the hardness with an aquarium tester, and go 193 ppm (they had .911) for KH...I wonder if they were doing parts per thousand? My GH was off the chart! Looks like I need a filter after all....
