    Control

    Taking care of your aquarium is super important for keeping your fish happy and healthy. It's a good idea to set up an automatic system to add water when it evaporates and to manage the temperature with heating and cooling. Using an Auto Top Off (ATO) system can make it even easier, helping you keep things stable without constant fussing.
