    Buying guide

    A clear, healthy-looking tank makes a real difference to how much you enjoy your fish, and a UV steriliser is one of the simplest ways to keep water looking its best between cleans, tackling green water and free-floating algae before it clouds your view. Running costs are low, and most units are designed to sit inline with your existing filter, so there's no need to change your setup. The key to getting good results is matching the steriliser to your actual water turnover rather than just tank size — if you're unsure how much water you're circulating, our fish tank volume calculator can help you work out what you need before choosing between our 5w to 36w models.

    Choosing the Right UV Steriliser for Your Aquarium
