    How do you test TDS?
    I have a RO/DI unit that produces 50 gpd +, it is rated for 35 gpd. I have it pumped into a 50 gal trash can with an old aquarium sump that is connected to a drip system. Total set up was cheap, easy to do, and takes little space in the corner of the yard.

    Hi CP30, to test for TDS you must either send it to a lab to have it tested, generally they must have at least 1 gallon of the sample water. Or you can invest in a TDS meter yourself. THey aren't terribly expensive, but if you want a quality one it'll be around $150 and can go much higher.

    I have a similar setup like yours for collection purified water. I also have my system on a float valve that automatically keeps a 45 gallon trash bin topped off, the misting system then syphons from the bin from the misting pump. I plan to have a much better water holding receptacle...one that is designed for water and won't spring leaks at the seams like plastic garbage cans do reguarly [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/mad.gif[/img]

    Thanks for the info on TDS, I also have a float/solenoid set up - it is great! My can is a heavy duty rubbermaid 45 gal trash can used commercially. It might spring a leak in a few hundred years I guess. I purchased it at Lowes, maybe Home depot for around $30.
    What TDS level do most cp's tolerate? As a former aquariast I think in terms of water hardness, is TDS similar?

    I just bought this one on ebay:
    R/O unit

    It's replacing my old Home Depot unit that the construction workers damaged. It seemed to me to be a good deal. They are pretty easy to set up, too. I also got a second tank for more storage.

    Just as a follow up, I received the unit, and it kicks ****! Easy to set up, and makes a LOT more water than my older one. For $80 plus $30 shipping. I'm in water heaven now.

    CApslock, looks like a nice system! To Juicy for CP's, don't let all that water go to waste and start up a reef tank! [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]

    Dustin, I hate to do this to ya man... but...

    I think it was under 100ppm, 150 for neps. TDS stands for total dissolved minerals, which I suppose relates to water hardness. When the TDS value of the water is high so is the water hardness, is that right?
