Frequently asked questions

For active algae blooms or disease treatment, run the sterilizer 24/7 until the water clears. For routine maintenance and prevention, you can run it continuously or set it on a timer for 8–12 hours daily.

Most tanks see noticeable improvement within 24 to 48 hours, with full clarity typically restored in 3 to 7 days depending on aquarium size and flow rate.

No. Beneficial nitrifying bacteria live on surfaces inside your filter media, gravel, and biological substrates. The UV sterilizer only targets free-floating bacteria, algae, and micro-organisms passing directly through the unit.

Yes. Constructed with durable ABS housing and a corrosion-resistant quartz sleeve, the unit is fully safe for freshwater aquariums, marine setups, and outdoor ponds.

Replace the bulb every 6 to 12 months. UVC light output degrades over time even if the bulb still glows blue. We stock official replacement bulbs in our store so you can easily swap in a new one when it's time.
