It is rated at 12W and sized for tanks of 110 to 240 gallons, and the black housing measures 16 x 10 x 13 cm (6.3 x 3.9 x 5.1 in). The unit weighs 812 g (1.79 lb) and is designed to sit below the waterline as a submersible pump.\u003c\/p\u003e\u003ch2\u003eWill this pump suit the tank you have?\u003c\/h2\u003e\u003cp\u003eSizing is listed for 110 to 240 gallon tanks. Before you buy, measure the glass or acrylic wall where the magnet will sit: the magnet base is made for tanks less than 0.47 inches thick.\u003c\/p\u003e\u003cp\u003eThe wave maker head is part of the whole unit, so it is the pump that runs, not the head on its own. The pump suits coral tanks, where the current carries food toward the corals and moves secreted mucus away.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eColour\u003c\/th\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStyle\u003c\/th\u003e\n\u003ctd\u003eSubmersible\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e4200GPH 12W, for 110~240Gal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eStainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eItem dimensions (L x W x H)\u003c\/th\u003e\n\u003ctd\u003e16 x 10 x 13 cm (6.3 x 3.9 x 5.1 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eItem weight\u003c\/th\u003e\n\u003ctd\u003e812 g (1.79 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNumber of items\u003c\/th\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat 12W and a 4200GPH flow rate mean in a large tank\u003c\/h2\u003e\u003cp\u003eThe motor draws 12W and is a waterproof pump, so it runs while submerged in the tank water. Flow is listed as 2 x 2100GPH, split across the two outlets, which gives the 4200GPH total on the size line.\u003c\/p\u003e\u003cp\u003eIn a large tank, that movement forms a water cycle and raises the amount of dissolved oxygen, and it also helps equalise the water temperature more quickly. The horizontal wide-angle surface at the front spreads the flow widely around the surrounding area.\u003c\/p\u003e\u003ch2\u003eHow does the pump attach to the tank?\u003c\/h2\u003e\u003ch3\u003eHow wide a tank wall does the magnet base fit?\u003c\/h3\u003e\u003cp\u003eThe magnet base is intended for tanks less than 0.47 inches thick. Used on its own, the magnet base with its thickened magnet can be moved freely along the tank wall.\u003c\/p\u003e\u003ch3\u003eIs the wave maker head a separate piece?\u003c\/h3\u003e\u003cp\u003eThe head is not a separate piece: the pump runs as one unit, and the head goes with it. The base ball turns 360°, which allows multi-directional wave-making.\u003c\/p\u003e\u003ch3\u003eWhat does the suction cup base do?\u003c\/h3\u003e\u003cp\u003eThe suction cup base reduces vibration while the pump runs, and it can be detached when the pump is not in use. That leaves the magnet base as the other way to hold the unit on the tank.\u003c\/p\u003e\u003ch2\u003eDouble outlets, a rotating base and the front protection shell\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTwo water outlets sit on the double head, and together they carry the 2 x 2100GPH flow into the tank.\u003c\/li\u003e\n\u003cli\u003eThe front cover has a reverse card slot inside and a protection shell outside, which works as an anti-pinch guard for fish.\u003c\/li\u003e\n\u003cli\u003eA stainless steel shaft runs in the impeller, and the housing is made of stainless steel.\u003c\/li\u003e\n\u003cli\u003eThe rotating base ball gives 360° of adjustment, and the head can then send flow in more than one direction.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"hygger","offers":[{"title":"Default Title","offer_id":44473809305663,"sku":null,"price":284.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/2409\/1199\/files\/hygger-aquarium-pump-4200gph.jpg?v=1794645194","url":"https:\/\/dogjointly.com\/products\/hygger-double-head-aquarium-circulation-pump","provider":"DogJointly","version":"1.0","type":"link"}
