What is a Tunze 3155 Aquarium Auto Top Off?

A Tunze 3155 Aquarium Auto Top Off (ATO) is an electronic water level controller that automatically replenishes evaporated water in your aquarium. It consists of a sensor that detects the water level and a pump that adds fresh water when needed. This helps maintain a stable salinity level and prevents potential harm to your fish and coral due to sudden changes in water parameters.

Why should I invest in two units?

One Tunze 3155 ATO unit is suitable for most small or medium-sized tanks. However, if you have a larger tank or multiple tanks, it is recommended to have two units for better coverage and redundancy. Having two units also ensures continuous operation if one unit fails or requires maintenance.

How does the Tunze 3155 ATO compare to other ATO systems?

The Tunze 3155 ATO stands out from other ATO systems due to its compact size, user-friendly design, and high-quality components. The sensor is magnetically attached to the side of your tank, making it easy to adjust for different water levels. The pump is also small enough to fit into tight spaces and operates quietly.

How do I set up the Tunze 3155 ATO?

Setting up the Tunze 3155 ATO is straightforward and can be done within minutes. First, attach the sensor magnetically to the side of your tank at the desired water level. Then connect the pump to a power source and place it in a container of fresh water near your tank. Finally, adjust the pump’s flow rate using the controller knob until you achieve the desired amount of top-off water per day.

What are some additional features of the Tunze 3155 ATO?

The Tunze 3155 ATO has various features that make it stand out from other ATO systems on the market. It has an integrated timer function that allows you to set specific times for top-offs throughout the day, reducing any chance of overflow or flooding. It also has an audible alarm that alerts you if there are any issues with either the sensor or pump.

Final Thoughts

In conclusion, investing in two brand new Tunze 3155 Aquarium Auto Top Off systems is a wise decision for any aquarium owner looking to maintain stable water levels in their tank(s). Its compact size, user-friendly design, high-quality components, and additional features make it one of the best choices on the market.
