condition RO water?
 

So, I have finally jumped on the RO wagon. I am hoping it will help with some nuisance algae.

My question is do people still use conditioners like prime when using RO?

Nope, RO/DI should be pure and ready to add salt.

And to add ...

Here in the GVRD we have chlorine
A RO system removes it, so you're good to go
Some provinces use chloramines so reefers have to use different cartridges, but you're OK with a stock unit

thank you folks. my unit is RO only. would that change your answers?

Thanks again.

Not mine

Depends on what you mean by RO only? Does it include at least one sediment & one carbon stage before the membrane? If so, you're ok. If there's no carbon stage before the RO membrane, the chlorine will destroy it.
