    Just bought an HM EZ meter on Amazon for less than 20 bucks.

    I'm in a condo also, and can't tap the water line. I've been using this system for years. http://www.airwaterice.com/product/1...-DI-Added.html Tap varies betwen 600 to 800 tds, comes out of this filter at 0. So it works well. Not a ton of output so it's good for small collections.

    Only thing is due to the high tds of the tap, I have to replace my DI filter every three to four months, the csrbon and sediment filters about every fourteen months. The RO membrane lasts for yrs though. Ours gets a lot of use as we use it for drinking water and humidifiers as well.

    Be careful using the water from stores. I once had one place I used jump from ten tds to over four hundred one week later. Use that tds meter each time.

    Definitely will be checking every time...what's the point of a nifty new gadget if I don't use it, right?

    Thanks though for the link. Will be considering small RO units in the future if I ever expand the collection beyond my current water needs.

    Received my EZ meter today...the name fits.

    Water in trays is 36-37 ppm, tap is 195 and my aquarium is 310.

    Well...

    Went to my LFS and had them fill up one of my 5 gallon jugs. Good thing I didn't buy another 5 gallons worth because I just checked the water...220 ppm!? That's worse than my tap.

    So I'm a bit peeved right now. Guess I'll be buying bottled water again and possibly saving up for an RO unit.

    first thing you need to decide is if you want RO water on demand....
    If so then you will want a system with a captive air tank (aka bladder tank, aka accumulator, etc)

    Then you need to decide on how pure you want your water to be.... under ideal conditions a RO will reduce your TDS by 98%, Realistically, this will probably be more like 95-96%

    So if you have 200 ppm tap, the RO water will be 10ppm, if you have 1000 ppm tap the RO output will be 50ppm, etc

    To remove what the RO membrane doesn't we use DI beads....

    Also, if your supply cannot maintain 45-50psig minimum, forget about buying a RO unless you install a pressure booster pump.
