Aquarium Auto Top Off System for Fish Keepers, 1pcs

Ideal for nano tanks, this automatic water refill system operates on the principle of differential pressure, making it both simple and practical. One of its key advantages is that it doesn’t require electricity; therefore, you won't have to worry about water supply disruptions due to pump or inductor malfunctions. To use it, all you need is a 0.5-1.5L (16.9-50.7 FL Oz) plastic water bottle. If you detect a leak at the bottle thread, this indicates a mismatch, and you should replace the bottle with compatible ones such as EVAIN, Coca Cola, or Fiji.

Additionally, this device features a built-in noise reduction system that effectively minimizes sound, although it may not be completely silent. The refill system is designed without screws, ensuring no damage occurs to your tanks. Constructed from corrosion-resistant ABS material, it is also suitable for saltwater tanks. You can customize the tubing length by manually cutting it, allowing you to adjust the water level to your preference.

This gadget is suitable for tanks with a wall thickness of 3-10mm (0.12-0.39 inches). However, it is important to note that it is incompatible with rimmed and curved fish tanks. For tanks with wall thicknesses of 3mm (0.12in) or 5mm (0.2in), a self-adhesive gasket is included for proper installation.

This automatic refill device is an invaluable tool for anyone traveling or on business trips. It is compatible with various types of aquatic habitats, including fish tanks, tortoise tanks, planted aquariums, and saltwater aquariums. If your tank exceeds 40cm (16 inches) in length, it is advisable to use two refillers for optimal performance.
