Tunze Osmolator 3155 Auto Top Off - almost all components completely new

The optical sensor on my own unit failed after ~1 month of use right before a vacation, so I purchased a second unit, nabbed the 5017 controlled from the new box and later had the failed controller refurbished by Tunze under warranty. You will receive the unused components from the new box + the 5017 controller I used for 1 month with its newly replaced and tested optical sensor by the manufacturer. I tested the optical sensor in a glass of RO water when it came back from Tunze to confirm that it is working correctly and can provide a video if requested.

Box contents:
- 5017 controller with sensors - controller is 1 month used without any salt creep or wear. Optical sensor is new, function checked by Tunze and has not contacted tank water
- Pump - new
- hose - new
- 12v DC power supply - new
- hose - new
- magnets, adhesives, bumpers, etc - new
- all manuals and packaging - new, no water damage
- receipt showing original sales date of 10/08/2022

$190 including shipping to your USA address, payment via paypal

Freshwater filter only or is it? Have you ever used an HOB filter on a saltwater tank?
