Answering my own question here. I suspect you are confusing DI with Ion exchange resins, which "trade" various salts for the removed contaminants.
A DI resin operates a little differently.
"Deionizers are complete “ion exchangers”. In a deionizer, water flows through a chamber filled with “cation” and “anion” synthetic resin beads. Millions of hydrogen ions (H+) are loosely attached to each cation bead and hydroxide ions (OH-) are attached to each anion bead. Passing water exchanges all its positive ions for H+ ions and all its negative ions for OH- ions.

Released H+ and OH- ions react with each other, forming H-OH or H2O, which is water."

And water, we all know, is good fer drinkin" ! [img]tongue.gif[/img]

looks like i will be getting a ro home filter...
for about the same price as the 100 gallon ro/di+shipping i can get a 50 gallon ro with the storage tank and drinking faucet...if i decide to add di in the future it will cost a mere $75.

<font size="2" face="Verdana, Helvetica, sans-serif">Keep in mind that the unit itself is from a US company and the Canadian company makes almost nothing on it. Don't get me wrong, they're great units, but if you can save a substantial amount of money by buying elsewhere without the shipping costs......

<font size="2" face="Verdana, Helvetica, sans-serif">Im realy talking about DI cartrige cation and anion, Drinking deionized water is not a good idea. First of all if dionized water comes in contact with metal, it will dissolve it into the water. If you drink pure water it will take minerals form your body becasue it is "Ion aggressive". Also purified water grows a great deal of psudemonas bacteria. Remember, you were told never drink water form a stagnant pond. Every drinking water system I have seen in a home is a stagnant pond. To stop water from growing massive amounts of bacteria, you must add an inhibitor (chlorine, choramine, Iodine etc...) or you must keep it moving at a constant 5 feet per second. If if you remove bacteria and then store it in a tank, storage bladder or in a pipe, it will rapidly re-grow bacteria.

I agree reef raf

Im not shure but I realy dont tink aquarium pro made a lot of money on those unit cause AJ dont buy them from wateraniwere.com but from aquafix who probably buy then from wateranywere cause there only two compagny who realy made purification product in US the first is DOW who is in fact wateranywere.com and another I dont remeber is name.

When I have orther mine it it was good cause nobody online where selling RO cheap like aquarium pro.ca do and the membrane was 25$ for a 100 gpd at water anywere but now maybe it is diferent as wateranywere have jump there price maybe you will not save a buch if you orther it from US take a calculator and count everyting dont forget the dam 30$ broker fee UPS ask

Stephane, the TDS meter from aquariumpros is 69.99 not 59.99... I'll buy one anyway!

Also, is it OK to use normal hosehold sediment filters found at Canadian Tire like this- Fine Pre filter - and this one- Chemical, Chlorine,Taste/Odour Cartridge- for the clorine removals?

[stephane]

Oups... I have pay that price six month ago
the price is higher
probably due to hour realy great money value!

Normaly Im alway in favor of buying ting in hardwar store but I found that for those cartrige you will not save a lot. On ting important is
that the sediment cartrige should be 1 micon and the carbon 5 micron if my memory is good

most of sediment cartrige from hardware store have higher micron so it will be more harder on your membrane since they are not made for RO but only utilize by there own without membrane but if you could find the right one and save some $ go for it

That hobby is so expensive so if you could find place where you could save some money and tell to
every one it will only contribute more to promote that hobby. I know it is important to support our LFS in paper and theory but I like more to spend that extra money save in my own tank for coral, fish , diner at restaurant or even send it to charity if you heart is very big. ;)
