Auto Top Ups

Auto top ups or auto fill systems are used to compensate for evaporation of water from your aquarium. The amount of salt in your reef tank is a key component to the success of your reef. As evaporation takes place the salt is left behind, and the salinity of your aquarium increases. Using an auto top up to replenish this water with fresh RO helps keep salinity stable in your tank.

We stock a wide range of auto top up systems and water change systems from brands including D-D TMC, Tunze and Neptune Systems to name just a few. In addition to auto top ups we also stock water change kits and water change pumps which can help you keep your tank’s water as fresh as possible while maintaining the right salinity.
