+Mlaw Posted March 17, 2014 Share Posted March 17, 2014 I'm planning on buying my first RO/DI unit. Any suggestions on brands? It's for a 210 gallon tank. I'm not exactly sure of all that is required here so any advice or suggestions on things to avoid would be appreciated. Quote Link to comment Share on other sites More sharing options...
Sherita Posted March 17, 2014 Share Posted March 17, 2014 I run a 100gpd system purchased from Melevs Reef. I'm very happy with it, and have had no issues at all. Marc is great to work with, and has promptly answered any questions I have had. Quote Link to comment Share on other sites More sharing options...
Viet'spride70 Posted March 17, 2014 Share Posted March 17, 2014 thefilterguys.com seems very good to have all u look for , and other sponsor sites in here. personnally i use 4stage RO drinking filter with additional DI canister and dual TDS meter from BRS. its been working very good for me in the past 4yrs now.

Jimbo662 Posted March 17, 2014 Share Posted March 17, 2014 I would also look at what your water change regimine will be to determine what GPD volume you should select. If you'll be doing frequent / large changes then you wouldn't want a 75gpd system. Quote Link to comment Share on other sites More sharing options...
+Mlaw Posted March 17, 2014 Author Share Posted March 17, 2014 I'm not planning on doing many water changes. 1 Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted March 17, 2014 Share Posted March 17, 2014 I run a system from the filterguys mentioned above. It has been running flawless and their customer support is amazing. I run a 75 gpd filter as I've always understood it as the lower rated membranes have a higher rejection rate. May be a nominal difference but I don't mind waiting a little bit longer for cleaner water. Since I only topoff and don't do water changes, it is even less of an issue. I will say it was brutal to fill up the 210 for the first time. I could see myself visibly age in the reflection of the glass watching the tank fill.

victoly Posted March 17, 2014 Share Posted March 17, 2014 I frankensteined one together. Since you're not planning on running SPS or anything super picky, you probably don't need to get as anal about chloramines as I did. 75 gpd membranes are the way to go, and if you want to increase your gpd, it's as easy as adding in another 75 gpd membrane.

FarmerTy Posted March 17, 2014 Share Posted March 17, 2014 That's what I have, the 75 gpd membrane stacked on another 75 gpd membrane, thanks to Brian. Where was that when I was filling my 210 gal for the first time Brian? I also run their chloramines kit since I'm about as anal as Victoly is about water quality when it comes to my SPS.

madsalt Posted March 17, 2014 Share Posted March 17, 2014 I use the 4 stage value system from BRS with the 150 gallon per day upgrade which I highly recommend. With this my waster water was cut in half. I also added a booster pump which allowed me to fill a lot faster. There is a picture of my saltwater change system on my thread with the RO/DI system.

+Mlaw Posted March 17, 2014 Author Share Posted March 17, 2014 why did that change your waste water? Quote Link to comment Share on other sites More sharing options...
+SChrisEV Posted March 17, 2014 Share Posted March 17, 2014 The 150 GPD is just a second 75 GPD membrane. You send the waste water from the first one through the second membrane. So you have half the waste water (roughly) that you would have had with just the one membrane. Quote Link to comment Share on other sites More sharing options...
Richard L Posted March 18, 2014 Share Posted March 18, 2014 BRS with the 150 gpd upgrade. I make about 100 gallons every two weeks. Had it for two years with no issues. Quote Link to comment Share on other sites More sharing options...

jolt Posted March 24, 2014 Share Posted March 24, 2014 Another good outfit is Buckeye Hydro (formerly Buckeye Field Supply). I bought my 75 GPD 'chloramine special' unit from them and have been happy with it. They also have very good tech support. 1 Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted March 24, 2014 Share Posted March 24, 2014 I'll second Buckeye. I've had my system from them for 5+ years without a hitch. That said, all of these systems are essentially the same and as long as you go with a respected supplier you will be good to go. Find the cheapest one and be done.
