Yeah, i have a coralife 3 stage system that attaches through the faucet.

Exactly. You can do a build your own ro system through bulk reef supply for cheap and they give you the option of the add on adapter for you faucet. I think they even give you an option for a diverter so you can leave it hooked up if you want. You can put together a whole system for less than $100
