Aquarium Systems Multi-Cycle Pump Timer 3 Adjustable cycled outlets Timing patterns from 20 seconds to 3 minutes 3 Standard power outlets This timer offers an excellent lower cost alternative to a full fledge wavemaker. The main drawback is this model does not have soft start which protects your powerheads. The Maxijet Brand powerhead is the only powerhead we would recommend for this timer since it's much more durable of a powerhead.
