The 6060 is 1600gph, the 6080 is about 2200gph. They are all the same size, roughly 4" square. They only come with speed control (electronic models only) but if you add one of our controllers you can make them pulse and have night mode and food timer. The 6060 and 6080 cannot be controlled in anyway, so unlike a maxijet absoutely no wavemakers. Unlike a standard powerhead, the prop only works if it spins the correct direction so it has a clutch to stop backwards rotation and this is destroyed by frequent on and off.
