My Game Changer - The Liquid Level Sensor (LLS)

Part of My Neptune Systems Gear Review Series

Adding the the Neptune Systems Liquid Level Sensor (LLS) to my protein skimmer was an absolute game changer. I no longer have to worry about overflows causing sever issues and I can enjoy camping and paddling boarding in peace.

For my 360 gallon reef community aquarium (550 gallons with sump and mangrove system) I use a Bubble-Magus 1000 protein skimmer, which I cut a notch in the collection cup lid for my 4" LLS and connected it to my Neptune Systems APEX Fluid Monitor Module. To control how it functions I programmed the Neptune Systems Energy Bar outlet used for the skimmer to turn-off the skimmer when the water level in the protein skimmer collection cup reaches 1" or higher on the LLS and to keep it off for 25 minutes, then turn back on.

The reason for 25 minutes is in my experience the water chemical imbalance that caused the skimmer to start to overflowing will have settled. So then the skimmer will start again and if it over-flows again it will shutoff.

Currently my LLS is not sitting on the bottom, it is hooked to the side of the collection cup, see picture 1, and is about 1.5" off the bottom. However, I have run it sitting on the bottom for a year and had no issues.

The Code

Here is the skimmer core code for the LLS using the "Control Type: Advance":

Fallback ON

Set ON

If LLS_SK > 1.0 Then OFF

Defer for 025:00 Then ON

As you can see in Picture 2, I have additional code in regards to the automatic feeder and an optical sensor.

Background

Neptune Systems Liquid Level Sensor (LLS) represents a significant advancement in aquarium automation, offering continuous and precise monitoring of water levels. Unlike traditional sensors that merely detect the presence or absence of liquid at a specific point, the LLS provides real-time measurements of water depth in both inches and centimeters. This functionality enables aquarists to effectively track evaporation rates, monitor dosing solution levels, and manage reservoir capacities.

Key Features:

• Comes in four different sizes- 4″, 15″ 23″ and 35″. Purchase from Bulk Reef Supply
  

• Continuous Monitoring: The LLS delivers uninterrupted tracking of water depth, facilitating timely interventions and informed decision-making.

  
  

• Versatile Applications: Suitable for use in mixing stations, sumps, auto top-off (ATO) reservoirs, all-in-one (AIO) tanks, and dosing containers, the sensor adapts to various aquarium setups.

  
  

• Integration with Apex Fusion: Data from the LLS integrates seamlessly with the Apex Fusion app, allowing users to visualize water levels through graphs and animations. Additionally, the system can be configured to send alerts or trigger specific actions when water levels deviate from predefined parameters.

  
  

Conclusion:

The Neptune Systems Liquid Level Sensor offers easy of mine. It is a modern solution for aquarists seeking precise and continuous water level monitoring. Its integration capabilities and versatile applications make it a valuable tool for enhancing aquarium management. However, potential users should be aware of the reported calibration and durability issues allow I have not encountered any issues with any of my LLS. Ensuring proper installation and maintenance, as well as consulting Neptune Systems' support resources, can help mitigate these challenges.
