Auto Top Ups

Instead of topping up your marine aquarium's water levels in one go, why not use one of our auto top-ups? These are perfect for anyone looking to automatically top up the water levels of their tank slowly and consistently. Using an included anti-wave level sensor, our auto top-ups are able to determine when to add further water from your reservoir to your fish tank. They also help to avoid issues with evaporation removing large quantities of water and affecting your aquarium's water balance.
