I have been searching the archives for people that have recently bought RODI setups and want to ask if anyone has any other suggestions? I dont know that I like the DI cartidges on top (horizontal) as I could see where water might slip through. Suggestions or thoughts? I want to stay around $100 + SH
Here are some that have been posted.

You dont have any issues with the DI cartidges being horizontal instead of vertical?

Nope, works just fine. I have only used mine a few times though, but know of numerous other people who have the same unit with no issues. What issues would there be with a horizontal DI?

Lots of folks have recommended it. I don't have it hooked up yet.
Make sure you get the one that comes with the extra, free filters....

I'm gonna need to get one of these soon for my reef tank. This is the one that was recommended to me before but I know nothing about these machines.

Are there better units available for slightly more price or is this one really good?
 
Personally, I don't know, I haven't hooked it up. LOL! A lot of folks, from this site recommend it.

+++EDIT+++
That specific RO/DI has a reserve tank, for just the RO, for drinking, so that it doesn't waste the extra DI water...I believe.
 
I got mine from Aquasafe Canada but I don't know if they sell on ebay anymore? BTW, my DI cartridge is horizontal and has worked fine for years.
 
Regarding horizontal versus vertical...

What I've *heard* said - but have no experience with - is that horizontal units can have channeling issues. Water may form a channel and not actually come in contact with much of the resin. I would speculate that it probably depends more on the quality of the packing of the resin more than it's orientation though.
 
they are a semi-local company for me out of Duluth, MN. The LFS by me carries their products and I have been very happy with them. It is far better them my Kent Maxima I had before.
 
Another thumbs up for thefilterguys.biz

I've purchased some DI stuff from them and had some questions before I bought. Lightning fast email responses to my questions and just plain nice people, it seems.

Correct. Plus, horizontal DI cartridges are usually substantially smaller than vertically mounted units.

I am a big fan of SpectraPure. Other than them, I would trust AirWaterIce.
