<p>PURPOSE:To provide a fish breeding filter device wherein physical filtering and biological filtering are effectively combined by simultaneously performing mechanical (wet) filtering and dripping flow (dry) filtering. CONSTITUTION:A filter device main body 10 is partitioned into three spaces, that is, a left tank 11, a middle tank 12 and a right tank 13 and the water inflow port 130 taking in the water of a fish breeding water tank is provided to either one of the tanks 11, 12, 13 and a filter member 40 is received in this tank. A nitrifying bacteria propagating dripping flow member 30 is received in either one of the remaining tanks and a submerged motor 20 sucking and pumping up the water in two tanks to distribute a part of the sucked water to a nitrifying bacteria propagating dripping flow member receiving tank and refluxing the remainder thereof to the fish breeding tank is arranged to the remaining tank.</p> |
