## Questions & Answers

**Q: Can this be used as the main pump or does it only work on batteries?**
A: Living in the Northeast we get some crazy weather. This pump should be used as a back-up. It will turn on when the power goes off as you need to plug it in the outlet next to the tank. And yes it does only work on the batteries...hence a battery back-up pump if you lose power. The electrical plug is a sensor that will sense when the power cuts off. It is very powerful and gets the job done. My fish love to swim in and out of the currents it makes!

**Q: Will it work with a 120 gal saltwater aquarium? or how many do I need?**
A: I asked a Penn Plax rep about our 125-gallon tank.  Here is the recommendation using this device: Penn Plax PEN-019 Air Pod Aquarium Air Pump For Power Outage Automatic Turn On Keeps Fish Safe Up to 55 Gallons   https://www.amazon.com/dp/B00BV41N00/ref=emc_b_5_t
from Penn Plax:
" For the 125 gallon tank you would need either 3 of the Pen-019 (totaling 165 gallons), or you could use 2 Pen-019 and 1 of the Silent Air B-11 (totaling 139 gallons).  You do not want less than what is needed for the sake of your livestock."

**Q: How much watt is this?**
A: Nothing states how many watts this is. Sorry

**Q: where is the air intake for this unit? can i add a secondary hose to move its location?**
A: It pulls air in the unit directly and a secondary intake tube wouldn't really be possible. You could add a "Y" connector for two output hoses.   Hope that helps.
