    Folks have brought up a good point. My local municipal water supply comes in at 45ppm and would be perfectly good for cp use. However, I'm on a well and it is badly contaminated with iron, and straight out of the well it reads around 500ppm, so the RO unit was a necessity.

    If in doubt, FIND OUT! ;-)

    As others have said, it completely depends on the quality of water at hand. My tap water originates from a very pure source near Mt. Hood and measures, on average, 18 ppm. I would go further to say that the minerals found within that small value are beneficial to the health of the plants. I feel more comfortable using this than I would distilled or RO water.

    Water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a health risk.
    Results presented here are from 2011 analyses or from the most recent year that tests were conducted in accordance with regulatory requirements. Some tests are not required to be performed on an annual basis. Information can be obtained upon request from the ECWA Water
    Quality Laboratory (716) 685-8570 or on the Internet at www.ecwa.org .
    AL = Action Level: the concentration of a contaminant which, when
    exceeded, triggers treatment or other requirements which a water
    system must follow.
    CFU/100 ml = Colony Forming Units per 100 milliliters
    MCL = Maximum Contaminant Level: The highest level of a
    contaminant in drinking water. MCLs are set as close to MCLGs as
    feasible
    MCLG = Maximum Contaminant Level Goal: The level of a
    contaminant in drinking water below which there is no known or
    expected risk to health. MCLGs allow for a margin of safety
    MFL = Million fibers/liter (Asbestos)
    mg/liter = milligrams per liter (parts per million)
    MRDL = Maximum Residual Disinfectant Level : The highest level of
    a disinfectant allowed in drinking water. There is convincing evidence
    that addition of a disinfectant is necessary for control of microbial
    contaminants.
    MRDLG = Maximum Residual Disinfectant Level Goal: The level of a
    drinking water disinfectant below which there is no known or expected
    risk to health. MRDLGs do not reflect the benefits of the use of
    mrem/yr = millirems per year.
    uS/cm = Microsiemens per centimeter (a unit of conductivity
    measurement).
    ND = Not Detected: absent or present at less than testing method
    detection limit.
    ng/liter = nanograms per liter = parts per trillion
    NE = Not Established
    NR = Not Regulated
    NTU = Nephelometric Turbidity Units
    pCi/liter = picocuries per liter
    RAA = Running Annual Average
    SU = Standard Units (pH measurement)
    TT = Treatment Technique: a required process intended to reduce the
    level of a contaminant in drinking water.
    ug/liter (ug/L) = micrograms per liter (parts per billion)
    Variances and Exemptions = State or EPA permission not to meet an MCL
    or a treatment technique under certain conditions.
    < = Less Than
    < = Less Than or Equal To

    It depends on the quality of the unit usually. I have a 75 GPD from Bulk Reef Supply, ran me about $200, and is of good quality. I've seen them down to around $100 at 75GPD but those are offbrand. More GPD is going to drive the price up as well. You'll find there are some extra features, such as built in TDS meters, with a lot of sellers that can alter the price as well.

    I have looked at units at Lowe's in the $100 - $175 range, though that was a few years ago. Don't know how good they are, didn't buy one.

    I would consult with Butch before purchasing a unit. There are many factors to consider - among them if the unit use "standard" filters and membranes that can be found readily. Some use odd size components and you have to buy them from one or two sources at inflated prices and get gouged on shipping.
