An aquarium drainage system having a filter, funnel, clear tube, sensor housing, light sensor, light beam generator, waste indicator light, primary valve, secondary/safety valve, safety cap and safety switch, as well as the other components shown in the drawings, wherein the filter comprises a vented plate that is placed under the gravel at the bottom of the tank to allow the waste to travel downward under the force of gravity to the funnel where waste is directed to the clear tube connected to the bottom of the funnel. The sensor sends a signal to the waste indicator light when blocked causing the special primary valve to open allowing the waste to drop and be collected in a bucket.
