Product details
Description
The FZONE Aquarium ATO with Controller is an advanced auto top-off system designed to combat the constant threat of water evaporation in both saltwater and freshwater tanks. Keeping water parameters stable is essential for aquatic life, especially in delicate reef and marine setups where sudden salinity drops can cause critical stress.
This automated system functions flawlessly by transferring water from a separate reservoir straight into your tank or sump to maintain perfect specific gravity levels. Featuring an upgraded dual optical sensor module measuring under an inch in diameter, the controller delivers extreme precision while seamlessly fitting rimmed, rimless, or sump tanks.
Built with innovative QST 2.0 security technology, it provides real-time overfill protection and sound alarms if a fill cycle exceeds safety limits. Equipped with a whisper-quiet micro pump capable of a two-meter lift height and a complete installation kit featuring strong magnetic mounts, this premium USA-imported system makes aquarium maintenance effortless and reliable.
How to use
- Mount the dual optical sensor module inside your aquarium or sump at your desired water level line using the included magnetic attachment.
- Secure the water output tubing above the highest water line using the mounting clip to prevent back-siphoning, and install the check valve.
- Place the micro pump into your fresh water or RODI reservoir tank.
- Connect the pump and sensor cables directly to the independent QST 2.0 controller unit, plug in the power supply, and tap the main interface button to calibrate and start automated operation.

FAQs
Is your setup a rimmed, rimless, or sump tank?
This versatile auto top off system is fully compatible with rimmed, rimless, and custom sump tank setups. The compact sensor module utilizes strong magnetic mounts that adapt easily to almost any configuration.
What is the glass thickness of your aquarium?
The high-strength magnetic mounts included in this kit are engineered to hold securely through aquarium glass or acrylic walls up to twenty millimeters or zero point seventy-eight inches thick.
How often should the optical sensors be cleaned?
It is highly recommended to wipe down the optical sensor surfaces approximately once a month with a soft, non-abrasive cloth. This simple maintenance prevents salt creep or organic biofilm buildup from affecting reading accuracy.
Is this FZONE aquarium system an authentic USA import available in India?
Yes, this is a one hundred percent authentic USA-imported product. Dropy sources these premium systems directly from authorized suppliers in the United States to guarantee genuine quality for Indian hobbyists.
What kind of water should be used in the top-off reservoir?
For marine and reef aquariums, you should always fill your separate water reservoir with high-quality RODI water. Only fresh water evaporates from saltwater tanks, so adding saltwater will dangerously raise your salinity.
