What do you add to your RO/DI water?

??? I'll let the experts answer this, but cloudy tap water is not a reason to get an RO unit. My tap water is cloudy sometimes. I think it is just air in the water.

What kind of fish do you have and what is the pH and hardness of your water?
 
As I was told, you have to add some of the nutrients back as RO water has none. The best thing is to mix RO/tap and then add something in. Salt won't be enough as you need other minerals. I use simply discus - you can use it for any fish. To get rid of cloudy water you would need to store it for a couple of hours with a powerhead in it to mix the water. I get cloudy water sometimes too and I use a storage tank to do my water changes. I think after 30 min or so, the water clears.

I don't think anything would happen if you add that water straight to your acquarium. It just would take around 30min for the water to clear.

"It's not ok"?

Out of curiousity, why specifically? Does the cloudiness of it go away? Almost all tapwater comes out cloudy at times (usually due to dissolved oxygen). Does it come out with high nitrates? a pH of 9? Why are you set on using RO water? It's got a hefty price tag on it and needs to be fiddled with to get back to 'usable.'

Do you drink your tap water?

Saying "I just said I'm using RO" (using quotes loosely there) doesn't help anyone understand the *why* behind what you're doing.
