steelhead77 Posted November 26, 2009 Share Posted November 26, 2009 This is a pretty good deal. I bought the 150 gpd version a month or so ago and am very happy with it. http://cgi.ebay.com/Aqua-Reef-RO-DI-Reverse-Osmosis-Water-Filtration-System_W0QQitemZ380179954285QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item58847dba6d By the time you buy a used one and then replace the old filters, you're into it for at least the cost of this one.

Kshack Posted November 27, 2009 Share Posted November 27, 2009 Be careful with a 150 GPD membrane. They get 150 by using a low rejection rate membrane and you will use up your DI faster ($). If your incoming TDS are low it will possibly work well, but if they are high I would suggest a 75 GPD membrane. Quote Link to comment Share on other sites More sharing options...
Algae Posted November 27, 2009 Share Posted November 27, 2009 Good tip, Thanks! I'll do that on my next replacement membrane. Be careful with a 150 GPD membrane.

steelhead77 Posted November 27, 2009 Share Posted November 27, 2009 Here in Albany, my incoming TDS is around 25-30, at that rate, I think the membrane should last awhile. Quote Link to comment Share on other sites More sharing options...
