## Questions & Answers

**Q: Do I need any other piece of equipment to run this, like a wavemaker, etc, or can I just plug it in and go?**
A: This does NOT make waves by itself!  You HAVE to buy the Hydor Wave Controler (and really need at least 2 pumps on either side of your tank), to create a wave effect.  I just bought a 425 and it has ok flow across a 20 long tank ( but no waves).  You can attach it to a regular timer if you just want to run it at certain times.  That was no good for me so I ordered another higher rated pump AND the wave controller.  I'll see how that works when I get it.  I wanted a "shimmer" effect from my moonlights.  To get this I needed to put it at the top of the tank to push the surface enough.  Now I have a slight shimmer.

**Q: I have a 25-30 gallon tank, which option is best?**
A: I have a darter tank that has about 25 gallons of water in it.  I just replaced a 500 GPH water pump with the 850 GPH circulation pump.  The water pump really blasted quite a jet of water across my tank.  The Hydor is much gentler, with a broader spread, but still seems to make for a nice stream simulation.  While the 500 GPH was about the maximum my tank could handle, the 850 GPH circulation pump is just adequate for a stream simulation.  My main reason for switching was the circulation pump only uses about 5 watts of electricity, while a 500 GPH water pump uses about 35.  I'm hoping to see my water temperature drop.  If you are simulating a swamp, however, I would not recommend this product at all.

**Q: What voltage does it run on: 110v or 240v?  Thanks**
A: 110v in my house here in the US!

**Q: What size and how many of these power heads should I get for 90 gallon reef**
A: I had two 1400 on my 90 and it's too much,  stirs the sand up.
