The Coralvue Hydros system utilizes a proprietary 4 way 0-10v Cable available at most aquarium retailers.

Our system is completely compatible with their cable and no purchases are necessary from us to get the aF4 running with Hydros. Simply install the cable per Coralvue's instructions and pick a color to use for the aF4(black, brown, yellow, red).

Identifying the Correct 0-10v Port

Depending on which port you have selected, you'll be using a different port in the Hydros app!

Coralvue has made this EXTREMELY simple for you by color coding the cables which correspond to outputs in the Hydros Application.

For this guide, we're going to select the BLACK output on the Coralvue Cable.
