For Trade Trade Red Sea RSK 600 Skimmer for Red Sea RSK 300

[oseymour]

I have a Red Sea RSK 600 skimmer that I bought used from another reefer here - The skimmer is just over a year old because they were release in January 2019.

Its way too big for my tank so I'll trade it for the smaller version. If you RSK 300 is new, I'm willing to throw in some cash or something else to make it work.
