The Hydor Flo is a rotating water deflector which rotates 360 degrees and is driven by the water flow of your filter. Can be attached (with included adapters) to most filters and pumps.
The deflector will move the surface of the water, increasing oxygenation and surface gas exchange. Creates a wave effect that is beneficial to plants and reef inhabitants.

Does what it advertises.... Review by Clinton
This is a very simple water movement deflector. Install it with a good pump (I use a maxijet pump.) and you're in business. The only issue I had was when small snails would get in them and stop it from rotating. Highly recommend taking them apart and cleaning them once in awhile. If anything gets to the plastic gears inside them they will stop the rotation of the deflector. (Posted on 6/5/2016)

Review by sal
Although a cheaper alternative to a wavemaker this thing is really great it moves the water randomly and prevents from blasting coral with straight linear flow all in all if you cant afford a wavemaker this is the way to go just make sure you clean it regularly at it will be a great alternative. P.S. it does reduce the flow of the pump being used so i would use the next size or two up to whatever you are going to choose Maxi jet was my choice (Posted on 4/9/2010)
