R/o, DI unit recommendations

Wolfman, splendid jackassery, but...

Let's review here - you made a statement - I asked you a legitimate question as to how you drew that conclusion - you respond with a smartass remark. Who's the jackass? For anyone who's read this thread or some of your other ones, I'm sure they already know...

With Kent Hi-S RO only, reportedly 98% plus of the silicates are removed. With a good prefilter set including a carbon filter, water quality is well within acceptable for fanciful TDS ideas.

"Reportedly"? Without monitoring the unit's performance (there's that "fanciful TDS idea") how do you know? Are silicates your only concern? The carbon and the prefilter definitely serve a purpose, but they don't remove everything.

I've run three separate systems over ten years without ever measuring the elusive and troubling TDS phantom

Nothing troubling or elusive about it for people who own an inexpensive TDS meter. How do you know when your RO membrane is not working well anymore?

Perhaps if you presented a scientifically supported, factually based argument on the oy vey problems of TDS, you would have a thread of credibility.

Yeah, you're right, it's obvious that YOUR arguments are way more logical and you've taken a much more scientific approach here. :roll:

But with out it, your opinion, is really just that, opinion.

The functioning of an RO/DI unit has little to do with opinion. A DI unit removes contaminants that your prefilters and RO membrane won't. Don't take my word for it - do some research. Nobody is telling you that you have to use one, but the above statement is fact, not opinion.

Taz:

Sorry for making a mess of your thread. Sounds to me like you're leaning toward an RO/DI unit - I'm sure that will work great for you. As you said, you really can't overfilter the water. Pressure changes can effect the performance of an RO membrane, but I couldn't say to what degree. I'd follow the advice others have given about calling Aquatic Reef Systems - they know their stuff. Good luck with it.
