Jose, that sounds just about spot on to me.

If I could only afford the Merlin life would be good!!
Some DI after the RO might bring that number to 0, but unless you're running a reef tank don't even bother, 005 sounds beautiful.

Am I correct? Randal, Paul, Russ??/:confused:

005PPM is pretty good for an RO unit, even with the margin of error on a TDS meter. Sounds like it's working pretty good to me....

Jose, I'm not sure why you water should look white, I normally collect my RO in a storage tank and preheat it which works well and keeps things stable.

If it's got bubbles in it, it's full of some kind of dissolved gas. Co2 is usually the one. Let it sit before use. If it has a foul odor (H2S) you'll have to additionally treat it.
