Question on RO system

A stand alone RO filter system alone will filter most of the pollutants out of your water, but most of us would strongly recommend you go the extra mile and use DI filters after the RO filter to reduce your TDS to zero. I'm not sure how much that system costs but I suspect you could get a much better price for a combination RO/DI drinking water system from either Buckeye Hydro or Bulk Reef Supply.
 
Hi!

I'd say install a separated and dedicated RO/DI system. For a better quality - pure - water, it must go on the deionization membrane. You'll have 0 total dissolved solids (TDS).

Spectrapure is the one I recommend. I have the 90 gpd unit, for reef starter. It comes with TDS meter and spare filters.

As you're building the house, plan a fish room or a water mix station room. It may be small, but definitely you'll not regret.

I have an unfinished basement, and I'll do a plumbing to the tank and my goal is to automate water changes.

Try to think ahead and again, you'll need a RO/DI system.

Also, there's a lot to consider also: for each gallon of RO/DI water, you'll throw away 3 to 4 gallons. Plan a way to reutilize the waste water on plants or other stuff. And don't drink RO/DI water.

Simple RO unit are mostly for drinking purpose. it probably wont put out 0 TDS. a separate DI unit will solve the problem.
 
That is definitely a setup for drinking water only. First their is no sediment filter, only a carbon filter before the RO membrane. Second, the particle size on the prefilter is too large. It is 10 micron and you want 1 micron or smaller. Also, I can't tell if those are standard size filters. If not, then that means you will have to buy their filters which means they are going to charge you 2 or 3 times more than a normal cartridge.

I would do as others have suggested and get a dedicated RO/DI unit for your tank and if you want it for drinking water you can buy a kit for it. I prefer Spectrapure but Buckeye, Air Water & Ice and BRS are good units also.

Nothing wrong with drinking RO/DI water, just some don't like the taste because it is so pure. Just realize DI is not "food grade" quality so some shy away from it.
 
Does your city use chloramines?

Mine does, and it turns out a 4 stage RODI I have is not sufficient enough. So I have to upgrade it to a 6 stage.
 
The system the OP refers to uses proprietary filters - meaning filters with an odd size or configuration. You'll get an unpleasant surprise when you go to replace them!

Even if you just want a drinking water RO, I'd steer clear of that sort of system. Get a system from a trusted vendor that uses standard sized filters.
 
Your water treatment quiz de jour:

Why is it a bad idea to send RO water from a pressurized storage tank on to a DI stage?

Good thought, and I can't say it's wrong - the faster you push the water through the less time the DI has to do its thing. But that's not the primary issue...

There's a lot of research and science behind this. There's many reasons for it, the largest being that something so unnaturally pure will absorb minerals from things that aren't.

There are more assumptions/incorrect information to that than real research/science..

If the ONLY thing your body was to consume was "pure water" day in and day out then there may be a "slight truth" to some of that.. But no one lives on water alone and there are plenty of "minerals" supplied to your body through food,etc... Check the TDS of your saliva too..

FWIW.. I drank RO/DI water (0 TDS) for years (8+) without issue..
I've only switched to RO because my wife didn't like the "lack of taste" to the RO/DI water.. Now I switched to drinking the RO water before the DI stage so there is some "TDS" (approx 4 TDS on my system) left in it for some "flavor"..
 
check out bulk reef supply, you can get a great ro/di setup for $300 that puts out 75g per day or spend an eta $30 and get a water saver unit that puts out 150g per day
