## Questions & Answers

**Q: Any time the pump looses power and reboots when it gets power back does it have to refill all the way to top line for measurement? Or is it a one time**
A: Yes it has to refill to the top sensor so it can recycle, also if water level goes way below sensor when it reboots it will only pump 3 times then red light comes back on so unplug and plug back in so it can pump remainder water to reach level you might have to do this several times( i hope not) usually once is sufficient, hope this helps.

**Q: Can I use it on a 40 gal ?**
A: Yes, it will work fine.

**Q: Will this still work if I put a longer tube on it?**
A: Sure

**Q: How do you install hose clamp on a rimmed tank?**
A: Just rotate it. It will fit.

### ⭐⭐⭐⭐⭐ UPDATE! On my bad review. My Thanks to Fzone! 🏆
*by W***Y on May 28, 2023*

6 Month suspicious Sensor FAILURE?….CUSTOMER Service Assisted me professionally and want to say thank you for making action a priority to a long term loyal customer!Cheryl made sure to send a replacement immediately! Even when I’ve had this for 6 months (again that’s more than 30 days!) And it was great! Cuz I’m going on vacation in 2 DAYS! And have this to help me not to even Worry about the tanks water level!Thank you to Fzone and thank you to Cheryl!And I hope you guys received the failure sensor I am sending you guys back for improving this suspicious sensor failure as well as getting to the bottom of fixing whatever components failed! And making this product on indestructible!

### ⭐⭐⭐⭐⭐ Works great!
*by J***. on April 11, 2025*

Works perfectly and looks very sleek/nice. I was topping off my 10 gallon every day before and now it just does it for me which is super convenient! Magnet is very strong so the sensor is secure. even with the small amount of surface movement i have it doesnt throw off the calibration. Pro Tip: the first time you prime it if its a saltwater tank and already at the correct salinity just have the pump in saltwater when it primes and then after that move the pump into the rodi water. that way it knows the tank size and you dont have to worry about it lowering the salinity

### ⭐ PUMP NOT WORKING
*by A***R on December 20, 2024*

THE LIGHT BLINKS WHEN THE WATER LEVEL DROPS BUT THE PUMP WONT TURN ON UNLESS I UNPULG THE POWER AND PLUG IT BACK ON. THEN IT STARTS TO PUMP THE WATER SO THE SENSOR WORKS BUT NOT THE PUMP WHICH DEFIES THE PURPOSE . TRIED CONTACTING THE COMPANY BUT MESSAGE WONT GO THROUGH
