Dosing and Auto Top Off (ATO) pumps and equipment offer you an easy way to keep up with the maintenance of your aquarium. Dosing pumps allow you to supplement trace elements, calcium, magnesium, alkalinity and other additives to your aquarium in a controlled way. Auto-Top off pumps and accessories are used to replace tank water lost to evaporation, allowing you to maintain a more stable aquatic environment.
