Hang on wet/dry?


Reefing newb
Ok so a kinda local women has a hangon wet/dry sytem she got with her used 90 gallon, comes with powerhead and protein skimmer(may be broke) But she only wants 25 plus shipping, so I can drive out and pick this up for 25 bucks... Are these decent filters for starting until I can get my refugium going? I can probably resell it for way more later on lol.
