## Questions & Answers

**Q: Could this be tapped into an existing monitor system to act as a secondary monitor panel?**
A: If you use the same sensors it will give you the same reading.  If a sensor goes out, both systems will give you a false reading.  If you want a secondary monitor get 4 more sensors then you would have a good secondary system.

**Q: all tanks are showing whatever the fresh water tank is reading. Might replacing this monitor fix that problem?**
A: All is reading if there is problem for frish cheack sensore

**Q: Im confused. Does this come with the sensors to put onto/ into the tank? Or do i have to buy those separate?**
A: It does not come with the sensors.  It has the standard hook-ups that snap onto the sensor ends.  My tank came with the sensors in it.

**Q: what sensors work best with this ?**
A: Kib manufacturers the sensor packs. The probes aren’t super important.
