Hydros Triple Optical ATO Kit
Overview
HYDROS Triple Optical ATO Kit delivers advanced and reliable auto top-off protection for your aquarium system. Designed to integrate seamlessly with HYDROS Controllers, this kit uses three highly accurate optical sensors to monitor water levels and provide redundant safeguards-preventing overfilling and protecting your livestock.
With its triple-sensor design, this ATO system offers a level of safety and precision beyond standard two-sensor setups. The first sensor activates the fill pump when water drops, the second confirms proper operation, and the third acts as a failsafe-offering multilayered protection you can trust. Easy to install and configure using the HYDROS App, this kit supports long-term reef stability by keeping salinity consistent and minimizing evaporation effects.
Ideal for sumps, nano tanks, and full-size reef systems, the HYDROS Triple Optical ATO Kit is built for reefers who demand performance and peace of mind from their automation gear.

Why Choose
Maintaining stable water levels is vital for a healthy reef tank. Manual top-offs are inconsistent and time-consuming-and many ATO systems fail due to single-sensor limitations. The HYDROS Triple Optical ATO Kit offers unmatched safety by using three separate sensors to ensure top-offs are performed reliably and stopped at the right time. Fully integrated into the HYDROS ecosystem this kit gives reef keepers the confidence to automate their system without sacrificing precision or protection.
