Auto Top Off Systems & Components

Auto Top off Systems are important for preserving the health inside your saltwater aquarium because it helps regulate evaporation and the salinity fluctuations that occur inside it. The water inside saltwater or freshwater aquariums is constantly evaporating and as a result, the amount of salt versus water fluctuates. This causes stress, or osmotic shock, on the marine life inside the tank. By installing an auto top system, the water gets automatically replaced when the evaporation occurs ensuring the quality life of your aquarium increases.

Auto Top off Systems are also great because they supplement the efficiency of your protein skimmers. Whether you are using the RLSS Protein Skimmer or the Tunze Protein Skimmer, when it runs alongside the Auto Top System, the protein skimmer’s  efficiency is increased by 40-60%! For help on the best AutoTop System and Protein Skimmers to use, let our professional staff at the top aquarium store in San Diego help you! Call us today at (858)467-9297 for all your aquatic needs.
