Teach me RO/DI

[Blood Shrimp]

So I've been using tap water. With tetra safe which supposedly neutralizes metals and kills bacteria. I want to get a RO/DI filter. What do these filters do, and where can I get a good one at the BEST PRICE?

tap water

YA RO/DI is a must.
There are a lot more things than you think in tap water. The RO unit will pull almost all of the "bad" stuff out nitrates, phospates, irons, silicas, clorines. DI is de-ionization of the water. It is like the last purifing section. Google RO DI and you will learn a lot of what it does.
If you keep using tap you will see algea grow and it will not stop.

I have looked a lot into spectrapure and the prices. There a few others that are good but price wise it will all come down to what you want to spend.

Check ebay. There are several sellers there that sell units at very low prices.

I got mine off Ebay. At first it did a poor job filtering. Now it is doing perfect. Took about 50 gallons to really do the job.

I would make sure you get the bigger DI bed before the little green ones off Ebay.

Yea I know why it's important, but just need a good price for a good unit. 55 gallon tank here. Don't need anything that big.

 

[twilliard]

Oh then YA Ebay it.

I payed 130$ for mine. 5 stage with tank.

So far the TDS meter says its flawless.

If you do ebay donot mention salwater or aquarium in search just ro/di water filter.

 

[twilliard]

I second that!
RO/DI in the search

Do they have to be permanently installed or can you just get portable ones that connect when you want to make water ?

I have a purifier now but it takes 1/2 hour to make 5 gallons. This requires patience and effort.

RO/DI is a must
check with your local walmart or LFS to see if they sell RO water.until you can get your RO filter. If you go to walmart
they might have a culigan water machine ,its 4 stage filtered water

 

[sc18702]

Is the culigan water amchine ro/di ? Sorry if i'm a bit dense.

 

[saltwater newbe]

yep RO UV Declorinater DI
4 stage

 

[mmkeeper]

You can have one that will hook up to a hose bib, you could put a Y fitting then connect your filter and your house. You just need a place for the waste water to drain. If you are talking about the culligan under sink filter with tank for drinking water, those are RO filters, they get rid of chlorine and other things but not nitrates and some other solids.

 

[sc18702]

Great, now I'm back to being confused. Is there one I can buy at walmart or similar place that will do completely dechlorination, large particles and can be hooked up to a sink or hose bib ?

 

[mmkeeper]

Most store bought fliters are only ro systems. Ebay for around $100. is a good place http://stores.ebay.com/Filter-Direct-store_W0QQssPageNameZstrkQ3amefsQ3amesstQQtZkm

Is there really a difference with all these RO/DI units? Some say they take out more stuff than others.

If it's an ro/di 5 stage filter ther's probably not much difference in the end product - clean water!
