Get a few powerheads in the tank so you can mix salt already!

That's not a bad idea ... hmmmm. Tomorrow!

Maybe your RO/DI is 100gpd membrane? Or you have higher inlet pressure? You're right, with a TDS of zero .., just run with it and be happy. I'm getting zero right now but it's all new prefilters and new DI. The RO is outputting steady at around 7. Not the best membrane I ever owned, the one before this one had a much better rejection rate or whatever the term is, it was almost always zero except for the first half hour or so. My DI lasted much longer on that membrane .. until the membrane went that is.
