What ro/di units do you use?

chip · 06-20-2002, 12:18 AM

Looking to buy a spectrapure ro di unit, however wonder what other units are available. Also, are most company units similiar or are some better then others. Currently using a marineploybio filter which is not working for me.

I get my water from a kent RO...(not the owner

)The Quality is great!

I've had an Aqua-Medic
RO/DI before, I didn't like it and neither did my fish.

I bought my last one from a place called Air Water and Ice. It was their 75gal a day five stage model one,and came with two extra prestage filter replacement cartriges. I'm pretty sure it was on sale,but they have very good pricing. When I got it it looked to be in a pretty old package,but that is the only thing I see wrong with it as it has served me perfectly. It fills my 48gal Rubbermaid overnight.

Hey Chip, try Aquatic Reef Systems. They have very nice RO units, I have had my Oceanus RO/DI unit for about 6 months and I am very happy with it. Their units are superior quality and their customer service is great. Call Bryan at ARS and he will set you up....

Is Oceanus and triton the same brand???

Sker · 06-20-2002, 01:35 PM

Northman, no the Oceanus is a model name (100 GPD RO/DI unit) that Aquatic Reef Systems makes.

I have a spectrapure 3 stage RO with an add-on DI unit... Has worked very well for me...

thezookeeper · 06-20-2002, 07:09 PM

I second the Aquatic Reef Systems unit. I've had my Oceanus 100 gallon/day since (yikes) Sept. 11, 2001. You can imagine how I remember that. It's worked fantastic and the customer service is great!

Man, Just order a unit today at aquaticreefsystems. Got to say I love it. The pricing is the best deal!

I have a RO/DI unit under my kitchen sink, but I think its purpose is just for drinking water. I've barely just got in the reefkeeping hobby and i'm such a newbie. But my question is, can I use that unit as my source water for top-offs and makeup water? I looked under the sink and it seems that some of the lines go through copper pipes. I know copper is bad for certain tanks but i'm too damn cheap to buy a real RO/DI unit dedicated for my tank. Any opinions or questions will be helpful, thanks.

So long as the copper line goes before the RO unit, then you should be fine. Before I bought my RO/DI unit, I used the one under my sink for topoff. The only problem was that it made only approximately 10 gallons a day.

My money and opinion goes to Bryan at Aquatic Reef Systems. Why? Great unit (Oceanus 100gpd), great service, great guy! You can't go wrong!

I bought my unit in December '01, it's working great. I went to Florida in Feb, 02, visited Bryan's operation, had lunch with the guy, (he bought

) and when he mentioned something about a bypass flush kit, I told him I didn't know about that, he gave me one.

I mean, how do you top this guy? Truth is you can't! Ooooops, sorry Bryan, You'll probably be buying a lot of lunchs now, huh.

philip711 · 06-25-2002, 12:00 AM

I have the 100 gallon per day four stage Tornado RO/DI unit with a built in flush kit and pressure gage, its a great unit, i get 0 ppm water for my 55 gallon tank. ---------------- My Ocean

**golfish** · 06-28-2002, 06:16 PM

The drinking water RO units don't filter as well as the made for fish tank units do. I have done a little research on this and found the drinking water RO membranes are a lower grade membrane.

BTW, I use a Specrtapure CSP 80 DI

**scubadude** · 06-28-2002, 06:55 PM

I have 3 RO/DI units

1 Oceanus 100gpd 4 stage with booster pump RO/ and Dual DI cartridge bought from ARS This is my favorite RO unit! This unit will take 500 TDS water and make it 3 TDS or lower and does it in a flash!

1 Spectra Pure 20 GPD RO unit....it works good and was my first one

bought from Jeffs

1 Tornado 3 stage RO/DI unit 55gpd bought from ReefPure....I know dont even say it!

Yes most RO units are the same....but I agree w/ Mark NOT the drinking RO units...those are not as good try to get an RO unit with a flush valve on it too! ARS you cant go wrong

Elmo18 · 06-30-2002, 08:12 PM

I'm using a Kent Marine 3-Stage model RO.

Works well so far. I would however, get the clear model next time, instead of this blue one. I can't see through it!!!!!
