It hides the downpipe plumbing and stops objects, food or fish from dropping into the overflow compartment.\u003c\/p\u003e\n\u003ch2\u003eWhat it's for\u003c\/h2\u003e\n\u003cp\u003eA REEFER's overflow box is the glass well in the corner of the tank where surface water spills down to the sump. Left open, it exposes the pipework, catches floating debris and stays an entry point for anything lying on the rim. The cover closes the top of it cleanly.\u003c\/p\u003e\n\u003cp\u003eIt's also the part you rebuy when the original has cracked, yellowed or gone missing — overflow lids are among the parts most often lost during a tank move.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eFits: REEFER 170, REEFER 170A, REEFER 170 G2, REEFER XL 200, REEFER 250, REEFER 250 G2, REEFER 250 V3, REEFER 250 V3A, REEFER XL 300, REEFER 350, REEFER 350 V3, REEFER 350 V3A, REEFER XL 425, REEFER XL 425 V3, REEFER XL 425 V3A, REEFER XL 525, REEFER XL 525 V3, REEFER XL 525 V3A, REEFER 525 G2, REEFER XXL 625, REEFER XXL 625 A, REEFER XXL 750, REEFER XXL 750-2, REEFER NANO, REEFER Peninsula 500, REEFER Peninsula 650 and REEFER Peninsula 650 A.\u003c\/p\u003e\n\u003cp\u003eYour model isn't on the list?

If you're moving your REEFER, set it aside with the screws: it's small, it's light, and it rarely makes it into the box.\u003c\/p\u003e\n\u003ch2\u003eComplementary products\u003c\/h2\u003e\n\u003cp\u003eTo stop fish jumping out over the top of the tank, the \u003ca href=\"\/en\/products\/red-sea-aquarium-net-cover-24\"\u003eRed Sea Net Cover\u003c\/a\u003e is cut to size, and the \u003ca href=\"\/en\/products\/red-sea-aquarium-net-cover-universal-cut-out-kit\"\u003euniversal cut-out kit\u003c\/a\u003e exists precisely to route the cover around the overflow box.
