But, if it's a one off, you have spare rock, and it does the job, that's all that matters.

I guess for medicating purposes it's definitely more beneficial to have a filter. I could buy 50 filter pads for what the rock cost me. But this was kinda a make do rushed tank to try and rescue a tang. Once he's better i'll have to reassess the setup and most likely relocate to an area where adding a 10 gallon sump would work. Then I can filter and protein skim. My tank is getting to the stage now where it's not worth not quarantining. Thanks everyone for the input. I'll update in a few weeks an let you all know how the tang does. Hopefully it all works out.
