It's the pin wheel of the Sicce PSK 1000 pump that drives this skimmer — the part that shreds air into fine bubbles to produce foam. Over time, a worn or damaged wheel reduces foam production; replacing it restores your skimmer's original performance.\u003c\/p\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRed Sea Reefer Skimmer 600 (RSK 600) with the \u003cstrong\u003eAC Sicce PSK 1000\u003c\/strong\u003e pump.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSpecific to the 600 AC model\u003c\/strong\u003e: the RSK 300 and 900 use different impellers.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDoes NOT fit the REEFER DC Skimmer 600.\u003c\/strong\u003e The DC model runs a completely different ReefRun DC (PSK DC) pump with its own impeller — the R50531 will not fit it.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e⚠️ Special order — final sale\u003c\/h2\u003e\n\u003cp\u003eThis part is a special order: \u003cstrong\u003efinal sale, no exchanges or refunds\u003c\/strong\u003e.
