    The topic says it all. Is it good or bad? Should I tell my girl to use it or get distilled?

    i have water that is about 161ppm. thats probably not very good for most CPs but i wonder if neps can take it? orchids also? it would make my life so much easier to be able to use water from my tap on orchids.

    EDIT: let me add what exactly we have
    pH-8.2 SU
    Calcium- 46 mg/L
    Hardness(as CaCO3)-145 mg/L or 8.5 grains/gallon
    Sodium-23mg/L
    Magnesium-12mg/L
    Alkalinity-(as CaCO3)-77mg/L

    anyone have any thoughts on those readings?

    I think you can find out your area water quality on a certain website, but I think you'd have to google it, I don't remember. You could also buy a fish water testing kit, and there are several tests like chlorine and water hardness.

    JM: just checked yours and your water hardness is about 134 ppm. if you can grow your plants with your tap then i will be able to...but lets get one of the pros in here to decide if we can first.

    IIRC, 100 PPM is good. 134 isn't THAT bad. I'd be more worried about the sodium and PH levels. You can add some vinegar to bring the PH down and flush with RO water to leech out the sodium. Mexican Pinguicula can take, nay, benefit for some added minerals including calcium, and some nepenthes can take higher mineral/nutrient content aswell.

    It's so much simpler to just buy water or better yet by an RO filter.

    I've been using tap for a long time on neps and orchids with no problem. Not sure what my PPM is but Sarra's and VFT's HATE my tap while neps and orchids love it.
    My life sucks
