A UV steriliser is a great tool for keeping your reef tank clean and healthy. By passing water through a chamber with ultraviolet light, it kills free-floating algae, bacteria, and parasites before they can cause problems. The result? Clearer water, fewer outbreaks of nuisance algae, and an extra layer of protection for your fish and corals.
UV sterilisers don’t replace your filtration, but they work alongside it to give your tank a boost in stability. Many reef keepers find they help reduce issues like cloudy water, dinoflagellates, and even marine ich by lowering the number of harmful organisms in the water column.
At iReef, we stock reef-safe UV sterilisers in a range of sizes, making it easy to find one that suits your aquarium. Smaller models are perfect for nano reefs, while larger systems can handle heavily stocked tanks with ease. Most units are straightforward to install, low-maintenance, and designed to run quietly in the background.
If you want clearer water and added peace of mind, a UV steriliser is a smart addition to your reef tank setup. It’s a simple way to improve water quality and keep your livestock healthier for the long run.
