RO/DI beginer question!

[aqua_carmen]

I just ordered a 4 stage RO/DI unit and it arrived today. I was just wondering if there is any steps before attatching it to a coralife floater valve. For instance, can I just hook it up and run the first flow of water into the tank.. Is there anything I have to do before using RO/DI water?

Thanks,
Carmen

Typically flush a few gallons of RO water down the drain before having it pass through the DI resin anytime you use new cartridges. You can get a lot TDS and carbon dust and such when you first set it up. Once you run a few gallons, you can add the DI cartridges back in and you are good to go.

I would disconnect the tubing from the pre-filters and run that for a few minutes to help wash out any carbon dust etc. from the pre-filters. Then I'd hook the line into the RO membrane and disconnect the tubing to the DI. If you have a flush kit or valve to control waste water, run that completely open for a few minutes. If not, don't worry about it. If you have them, run them wide open for five or ten minutes and then pull it back to a normal 4:1 ratio of waste water to output water. Run water through the membrane for an hour or two, and then connect it back to the DI. Make a few gallons of water with the RO/DI and discard it. Then you can start using the RO/DI water in your tank. It's always best to flush everything out, just in case there are any manufacturing residues etc. that need to wash out of anything, which would keep your initial water from being completely pure.
