RO/DI versus LFS water

dstalfire · 06/16/2006, 12:59 PM

Sorry to post this twice, but in this forum you guys really now your stuff.

I found I can get an RO/DI unit on ebay for $130. I was wondering what the pros and cons are and what you would suggest. My LFS charges $.85 for salt and $.35 for fresh.

Thanks

Dan

I agree.

I just got back into the hobby a month ago...I've alread spent $75 on SW and RO water.

Here are my mixing station plans...I'm just waiting in my John Guest connections.

If you have your own RO unit you know when the filters were changed. You have control.

Does this look like a good unit?

from that link

Water Purity Reference: (1.)Tap or well water(300 PPM), (2.)After RO system(20 PPM),

if it was a true RO membrane removing 98%, the ppm after the RO would be 6ppm, not 20ppm. so what there calling an "RO membrane" is really a micro filter.

look at some of these

they might be a little more $ but you get what you pay for

Here is the one that was recommended (after I had already bought a lesser one)...
