Auto Water Filler, Plastic Nonelectric Water Level Controller Auto Top Off System Adjustable Valve Mounting for Aquarium Fish, Adjustable Tube Float Valve Kit for Aquarium Water Purifiers (1 Float + 3Connect)

Tool-Free Install, No Power: Clip the bracket onto glass or acrylic up to 15 mm (0.59")—no wiring, pumps, or tools needed. The float valve automatically tops off as water evaporates.

Adjustable Waterline (0.5–15 cm): Set your exact water level with the height-adjustable float; a built-in valve lets you fine-tune the refill rate for smooth, splash-free top-offs.

RO/DI Ready 1/4" Tubing: Connect directly to standard 1/4" OD water line from an RO/DI system or a gravity-fed reservoir (not included). Includes connectors for quick hookup.

Stable, Durable Bracket: Rigid, heavy-duty plastic mount holds position securely and resists bumps—no metal parts in contact with water.

Fresh & Marine Compatible: Keeps parameters steadier in sumps or display tanks; ideal for freshwater and saltwater aquariums seeking consistent water levels with minimal upkeep.
