Reverse Osmosis Help!

[rhiannoncum]

Hi,

I am looking into buying a reverse osmosis system for my new marine set-up.

A quick question . . . . .

Does the system run all the time like a protein skimmer, or do I just use it when doing water changes

Please help!!!!

Only need to use it whenever doing water changes.

Edit: Just noticed you accidently posted this twice - good to get another opinion I guess.

And you use it for FW top up, when you get significant evaporation, if you get it. But, Eelzor is right, nope, just run it when you need the water!
