Ro/di

BPBELL · Apr 3, 2013

I'm getting ready to upgrade my RO system to an RO / DI
I want the best quality water possible but everyone claims theirs is the best
I need about 75gpd
Dies anyone have a suggestion of what brand and model to get
I have a 220g DT that I'm building a reef in

All of the major brands will work. I have a 75 GPD Purely H20 Optima Vision. The major differences come in the type of filters. You would want .5 or 1 micron filters. They will allow your DI to last much longer. The "value" systems usually come w/ 5 micron filters, you will eventually need to replace them.

www.spectrapure.com is clearly the winner. No other vendor or manufacturer specially treats and tests their RO membranes, uses the much better absolute rated sediment filters, researches and blends their own DI resins fresh in house every day or uses capillary tube flow restrictors you yourself adjust according to your unique water conditions and has been in business doing just that since 1985. All these things add up to increased filter and component life, better water quality and a lower cost of ownership and operation for you the end user. There really is a difference.
