I want to purchase my first RO Unit and really know nothing about them. I was looking at the Coralife Pure-Flo II, the 4 stage 50gpd one. A couple questions off the top of my head are:

I have been reading a lot about the different units coming with a hose and what not. Is there an adapter or something that hooks up inside to a sink faucet or anything?

Is this type sufficient of unit sufficient? Anyone know anything about it?

This will be for my 90g tank. I was hoping to set it up and place the tub into my utility room. The reason I ask about the faucet is because it is too cold here to let it run very much nor can I mod anything on the house since it is base housing.

TIA, Rick
