## Questions & Answers

**Q: how does it restart after siphon break due to power outage**
A: It should not break the siphon when the power goes out.  The water level on both sides of the overflow pipe will remain submerged when the water stops flowing, preventing any air to get into the tube, causing the siphon break.  When the power comes on, the system will automatically restart when the water level in the tank exceeds the height of overflow container in the tank.

I've had several outages that did not result in any overflow of the tank.  However, I have had air get into the overflow tube and restrict the amount of water that can move through the pipe causing the tank to overflow.  This was caused by biological growth in the tank side causing air to be pulled into the water, causing air to accumulate in the overflow pipe.  Regular maintenance will prevent this from happening.

**Q: What is the measurement on the outside of the overflow? Widest point from glass to backside of overflow?**
A: From the outside of my aquarium to the outside edge of the overflow device is 3.25"

**Q: What's the flow rate for this what size return pump would you need?**
A: The flow is rated at like 200 gallon per hour. I do have mine set up on a pump that pushes 400 minus some loss for elbow joints and head height.

**Q: do you have to drill a hole in the tank**
A: No holes to drill. Hangs over top of tank.
