Its dual-siphon hang-on-back configuration uses two smoke-coloured U-tubes to transfer water over the aquarium wall and into the external drain chamber.\u003c\/p\u003e\n\u003cp\u003eRated for aquarium systems up to 200 gallons and flow rates up to 1,200 GPH, the PF-1200 is the highest-capacity model in the current Eshopps Power Flow line. Its compact acrylic construction requires only approximately three inches of rear clearance while providing dual 1-inch drain connections for larger sump systems.\u003c\/p\u003e\n\u003ch3\u003ePF-1200 Dual-Intake Overflow Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTransfers aquarium water to a sump without drilling the aquarium\u003c\/li\u003e\n\u003cli\u003eDual smoke-coloured U-tubes provide high-capacity siphon flow\u003c\/li\u003e\n\u003cli\u003eTwo 1-inch bulkheads support dual drain plumbing\u003c\/li\u003e\n\u003cli\u003eSlim internal pre-filter box minimizes display-space intrusion\u003c\/li\u003e\n\u003cli\u003eHigh-quality acrylic construction is designed for continuous aquarium use\u003c\/li\u003e\n\u003cli\u003eRecessed external overflow cover helps reduce splash and operating noise\u003c\/li\u003e\n\u003cli\u003eCylindrical pre-filter foams help keep larger debris out of the drains\u003c\/li\u003e\n\u003cli\u003eAdjustable mounting hardware supports proper water-level positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eEshopps PF-1200 Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEshopps item number: 89044\u003c\/li\u003e\n\u003cli\u003eDimensions: 10 x 3 x 10 inches\u003c\/li\u003e\n\u003cli\u003eMetric dimensions: 254 x 76 x 254 mm\u003c\/li\u003e\n\u003cli\u003eRecommended aquarium size: Up to 200 gallons\u003c\/li\u003e\n\u003cli\u003eMaximum flow rate: 1,200 GPH\u003c\/li\u003e\n\u003cli\u003eMetric maximum flow: 4,542 LPH\u003c\/li\u003e\n\u003cli\u003eIntake configuration: Dual\u003c\/li\u003e\n\u003cli\u003eU-tubes: Two\u003c\/li\u003e\n\u003cli\u003eDrain connections: Two 1-inch bulkheads\u003c\/li\u003e\n\u003cli\u003eOverflow style: Hang-on-back siphon overflow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePF-1200 System Planning and Siphon Notes\u003c\/h3\u003e\n\u003cp\u003eAllow enough clearance behind the aquarium for the external overflow box, drain fittings and connected plumbing. The return pump must be sized according to the actual flow delivered after head-pressure loss and should not exceed the PF-1200's maximum rated capacity.\u003c\/p\u003e\n\u003cp\u003eBoth U-tubes must remain completely filled with water during operation. Trapped air, algae growth or debris inside either tube can reduce siphon capacity and create an imbalance between the aquarium return flow and overflow drainage.\u003c\/p\u003e\n\u003cp\u003eEnsure that the sump has enough reserve volume to hold all drain-down water when the return pump stops. The complete system should be tested during normal operation, shutdown and restart before being left unattended.\u003c\/p\u003e\n\u003ch3\u003eEshopps PF-1200 Installation Directions\u003c\/h3\u003e\n\u003cp\u003eHang the internal pre-filter box inside the aquarium and place the external overflow chamber directly behind it. Adjust the mounting hardware until the assembly is level, secure and positioned at the desired aquarium water height.\u003c\/p\u003e\n\u003cp\u003eConnect appropriate drain plumbing to both 1-inch bulkheads and route the lines securely into the sump. Prime both U-tubes completely and confirm that no trapped air remains before placing them between the internal and external boxes. Start the return pump and verify stable siphon flow through both tubes.\u003c\/p\u003e\n\u003cp\u003eShut off the return pump to confirm that the sump safely accommodates all draining water. Restart the pump and verify that circulation returns to normal. Inspect and clean the U-tubes, pre-filter foams and overflow boxes regularly to maintain dependable flow.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEshopps PF-1200 internal pre-filter box\u003c\/li\u003e\n\u003cli\u003eExternal overflow box with recessed cover\u003c\/li\u003e\n\u003cli\u003eTwo smoke-coloured U-tubes\u003c\/li\u003e\n\u003cli\u003eTwo cylindrical pre-filter foams\u003c\/li\u003e\n\u003cli\u003eTwo 1-inch bulkhead fittings\u003c\/li\u003e\n\u003cli\u003eNylon screw and wing-nut adjustment hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eALL SALES FINAL ON CLEARANCE ITEMS NO RETURNS, REFUNDS OR EXCHANGES.\u003c\/span\u003e\u003c\/strong\u003e\u003c\/h4\u003e\n\u003c\/div\u003e","brand":"Eshopps","offers":[{"title":"Default Title","offer_id":52020279148832,"sku":"ESH-OF1200-OP","price":168.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/8222\/5696\/files\/esh-of1200_e6897943-fd0f-4f24-bb99-f68609113f0c.jpg?v=1784763443","url":"https:\/\/aquariumsupplydirect.com\/products\/eshopps-pf-1200-overflow-box-open-box","provider":"J\u0026L Aquatics - Aquarium Supply Direct","version":"1.0","type":"link"}
