This creation is a kind of tidal fish and vegetable symbiotic siphon group.Including an outer filter cover,One inner tube,A water conduit,The outer filter cover can be made of transparent material.It is a hollow ring shape.With ring wall,Bottom wall,Central accommodation,And a plurality of water inlet holes are arranged on the outer edge below the ring wall.And a through hole is arranged in the center of the bottom wall；The inner tube can be made of transparent material.And the length is less than that of the outer filter cover.The diameter of the chamber is smaller than that of the outer filter cover.Larger than through hole diameter,And an upper cover part is arranged on the top of the inner pipe.And the upper cover part can cover the upper part of the accommodation chamber.And a number of air holes are arranged at the outer side of the inner tube corresponding to the upper cover part.And the diameter of the water conduit is smaller than that of the inner pipe,With water inlet at the top,And the through hole of the external filter cover is closely connected with the inner wall of the through hole.And the upper position is in the inner pipe.The height of the water inlet is higher than that of the water inlet.The outer wall of the water guide pipe and the inner wall of the inner pipe are provided with a water inlet space；With this creation, the larger planting medium and external impurities can be prevented from entering the siphon group to affect the siphon function.And it has better effect of stable implementation.本創作係一種潮汐魚菜共生虹吸管組，包括一外濾罩、一內管、一導水管，並該外濾罩可由透明材質製造，並為中空環形體，具環壁、底壁，中央具容室，並於環壁下方外緣設置複數入水孔，又於底壁中央設置透孔；又該內管可由透明材質製造，並長度小於外濾罩長度，直徑小於外濾罩之容室直徑，大於透孔直徑，又於內管頂部設置上蓋部，並上蓋部可蓋合容室上方，又上蓋部對應內管外側位置設置數透氣孔；又該導水管直徑小於內管，頂端具進水口，並穿插外濾罩之透孔與透孔內壁密合，並上方位於內管內，並使進水口高度較入水孔高，又該導水管外壁與內管內壁間具可進水空間；藉此本創作可阻擋較大種植介質及外部雜質進入虹吸管組影響虹吸導水功能，並可具較佳實施穩定功效。
