Insane flow from a stealthy package The WAV moves water. Plain and simple. For its size and power consumption, it is in a class by itself in terms of the volume of water it moves. The WAV is much smaller than all other similar flow, in-tank powerheads. Surprisingly, it only a has slightly larger footprint than just the wet side portion of the most popular wavemaking pump on the market without having an obtrusive, noisy motor hanging on the outside of the glass.
