    Probably not, as long as you top water all the time and still use your rainwater. In fact, you could mix rainwater and tapwater and get water that is lower in TDS than your tap! I would do that if I were you.

    Cool! The big trash can (it's on wheels) is great for me.

    My membrane is already temperamental. The lowest ppm water I've seen is 17 from the thing

    I think mine comes out between 30 and 60ppm depending on the time of year and how rainy it's been. When the RO unit is done with it, it's all the way down to 1ppm - sometimes it'll oscillate between 1 and 0.
    I've been meaning to reclaim the wastewater, even though water is included in my rent. I'd like to store it out on my porch for watering my veggies and other non-CPs.

    Hopefully my picture series got you thinking about reclaiming again!

    Wow. your membrane is really efficient. I'm sure the low ppm starting water REALLY helps though. My distiller gives me 2-0 ppm water, but it's expensive to run, unfortunately.

    I just recently discovered that my waste water is safe for fish!

    I don't even need tap water conditioner. I wouldn't count on my findings though. Your water may be different. Anyway, I strung together several old siphon tubes to fill up a 100 gallon aquarium. It worked really well! The fish liked the gentle stream much more than the hose.

    To find out if your waste water is safe, place a couple aquatic snails in a bucket full of it. If they are still alive after a couple of days, your water is probably safe to use on your fish. The next step is to actually test a fish, but it's probably unnecessary unless your fish require special water parameters.

    I think I'll pass on the fish thing.....I don't want all that crap and heavy metals in my fish water.
    Some days it just isn't worth chewing thru the restraints.

    Get a digital ppm meter.

    LOL, I understand. These are paradise fish that I breed outside Not too expensive, and I have a nice supply of them.

    Aquatic snails are supposed to be (at least the chinese mystery snail) a good indicator of water quality. The particular species I have closes up when the water isn't quite safe. I have my snails in that grey trash can all the time, and they are always out and about.

    There is one thing you need to remember: my tap water isn't filthy to begin with. And my waste water, obviously, doesn't do my fish any harm. Therefore, I will use it because I don't have to use water conditioner to remove the chlorine. Of course I don't expect this to be constant, so I'll be wary of using it and will test it on my snails quite often And when the carbon block filters go, I think I'll know.
