Elos OsmoController Digital Water Level Controller

The entirely new OSMOCONTROLLER Digital uses a patent pending sensor with no moving parts as the first measure of the water level in the SUMP. Most other systems will use multiple float switches or sensors to act as back up to the initial float switch, elos does not. We believe the float switch or sensor will always be the weak link as it is usually a moving part and/or in direct contact with the water, most of the time. To provide an adequate fail-safe the OSMOCONTROLLER Digital uses a small microprocessor in combination with our patent pending sensor to control the pump and monitor the top off of your system. In the event of a fault such as an empty reservoir, a damaged pump or kinked tube, the microprocessor will recognize this and a red alarm LED will indicate the problem and stop pumping until the problem is fixed and the controller can be reset. The OSMOCONTROLLER Digital also has a manual top off button that can be used to use the system as a pump for occasional water changes and to fill a container with RO/DI water easily.

The set up of the OSMOCONTROLLER Digital is very simple. It works with most sumps without the need for programming and with our sensor design has a built in buffer for waves and small changes in the sump that will normally cause a top off system to unnecessarily top off, which will shorten the useable life of the top off pump.

Key Benefits of the OSMOCONTROLLER Digital:

• No moving parts
• Very easy setup. (System runs a 5 minutes self-diagnostic test when it is first plugged in.)
• Maintains a very accurate level, very important in marine systems for a stable salinity level when keeping delicate animals.
• Adapts to most aquarium/sump sizes automatically.

Octopus motorized (ANC) Automated Neck Cleaner helps keeps your octopus protein skimmer running at peak performance by periodically wiping the inside of the neck where all the bio-organics usually would accumulate.  This great skimmer accessory not only keeps you skimmer running at peak efficiency but save the timely chore of keeping your skimmers neck clean. As you know, build up in the neck causes foam to stick to the sides and restricting the collection of skimmate within the skimmers cup.

SRO Dual Blade Auto Neck Cleaning Device

Keeping the neck wall clean results in consistent skimmer performance and little to no down time.  This device uses twin squeegees to automatically remove the buildup from a skimmer neck. The SRO (ANC) consists of a high torque low RPM motor, wiper mount, lid with mounting clamps and the squeegees.

To operate this easy to you device,  you simply plug the unit into a timer (not included) or aquarium controller and set it to run for a few minutes 4 to 6 times per day.  By running it this way you will never experience crud build up along the walls of you skimmers neck.  This will  eliminate the daily chore of cleaning for two or more weeks while maintaining the level of skimmate production that you would normally get with only a freshly-washed collection cup.

This unit will increase the height of your skimmer by approximately 4.75“ with all models except the CL110 which adds an additional 4″.

Our Octopus ANC does not require you to send in or modify your stock lid in any way because our ANC is built into the lid for precise control.
