Hey Nick!

I recommend upgrading to the Fathom RV Tank Monitoring System. Unlike traditional probes that sit inside the holding tanks and can get covered in buildup, Fathom uses radar sensors mounted on the outside top of your plastic tanks to measure water levels without ever touching the liquid.

They offer kits based on how many tanks you need to monitor:

1 tank: # FM998FR

2 tanks: # FM498FR

3 tanks: # FM398FR

4 tanks: # FM698FR

5 tanks: # FM798FR

6 tanks: # FM898FR

All six kits include Bluetooth connectivity, allowing you to check your tank levels through the Fathom app on your phone without installing another display.

The 4-, 5-, and 6-tank kits also include a network hub for connecting to compatible RV-C monitoring systems, like your Victron Cerbo GX # VN23VR. The smaller 1-, 2-, and 3-tank kits don't include that hub, but we carry the Fathom Network Hub # FM598FR separately if you'd like to add RV-C connectivity. You'll just need to verify the necessary wiring and system configuration.

Fathom has told us they've had good results with Victron systems, so this would be a great option for your setup!

How many holding tanks are you looking to monitor?
