I saw a post on craigslist for a CPR skimmer (no mention of which one) and a fluval 304 filter. The question is whether to buy either. They are $45 each.

I have never had a canister before but my end goal is to have a 45 gallon tank with a 20 gallon refugium. Will there be any need for a canister to do
mechanical filtration if I have LR for biological, the skimmer removing DOC's and the refugium/sump doing it's thing (i'll learn what it does before I set it up)

Right now I have the 20 gallon operating as its own tank and a 45 gallon waiting for parts to make it legit. The only question is is the deal good enough to buy and hold? I know you'll want to know about what kind of CPR but I haven't heard back yet. I'll post when I find out.
