HYDROS Triple Level ATO Kit

A complete auto top-off kit that turns any HYDROS controller into a triple-point ATO system for small tanks and all-in-one aquariums.

• Triple-point optical water level sensor — no moving parts to foul or stick
• Includes a HYDROS DC Micro Pump (74 GPH, 8 ft max head, 12V/4.5W, GX12 connector)
• ~80" of 8.5mm OD / 6.5mm ID tubing
• Hang-on tubing mount and siphon break included

A single float switch only tells you high or low — three optical sense points add a safety cutoff on both ends, so a stuck float or an empty reservoir can't overflow a tank or run the pump dry.

Includes: triple optical water level sensor, HYDROS DC Micro Pump, tubing, hang-on mount, siphon break.

Compatible with: HYDROS Control X2 and X4 (requires an available Sense Port and Drive Port).
