Which is the best RO/DI unit?

[fayzane]

I am hoping to purchase my own RO/DI unit in the near future and am uncertain which is the best one to select.

All I know is I want clear containers so I can see the media. I have a 24g Aquapod so making 100gpd isn't necessary. I'm looking for quality and ease of use. Someday I'd like a 300g reef but that's well into the future.

Anyone have opinions on Kent systems, MarinePro or Maxpure? Any advice/guidance would be extremely helpful.

I'm no expert when it comes to RO/DI units but I can give you a recommendation on where to look for one. Air Water and Ice recently sponsored one of our PSAS fundraisers. I checked them out online and they have a good selection of RO units and accessories at good prices. They have also been helpful and responsive when I email them with questions.

Spectrapure and AquaFX for me

Both are pricey but not too bad.

I like my Puretek so far. I've made over 800g already and still 0 TDS.

I bought my RO/DI from here. It was cheap and I just changed my filters after about two years. They were only at 2 tds. With the filter change it is back to 0tds

Haha! I forgot to check what brand you had when you were showing it off at the last meeting...great price!

Aside from the filters inside the unit, most RODI's are very similar. Some have extra features like pressure gages, back-flush, ATO, and TDS meters just to name a few... Most all of which can be added on to just about any RODI unit later on should you choose to do so.

Filterguys can make a filter array recommendation for you based on your municipality's water quality, and I hear that they have phenomenal customer service as well. And the filter array is important because water quality can vary greatly from place to place. For instance, I have a friend that lives right down the street from me(about 4m), and he burns through filters like nobody's business, yet I've been using my original filters for a looong time and still have zero TDS. We both employ the exact same RODI unit.

I chose the AirWaterIce TyphoonIII Extreme because I like the fact that all of the filters ride on the same chassis. I just think it looks sharp.
