RO units are very wasteful and I don't believe you should use one unless you need to.

I'm not sure where Chilliwack gets their water from.. but here in Coquitlam (about 1 hour away from Chilliwack) I get 12ppm on ym TDS meter right from the tap. I just use a DI unit. Works for me and many other local reefers.
