Installed the clarifier with my Fluval FX filter in under 10 minutes. Water clarity improved noticeably within a week. The unit runs quietly and the light indicator helps me know when it’s active. No issues with algae or bacteria in the tank.

Works well with my existing filter setup. The water looks much cleaner, especially after heavy fish feeding. The bulb lasts longer than expected and stays cool during operation.

Great addition to my 55-gallon tank. Algae in the water column has reduced significantly. Easy to install and the IP44 rating gives peace of mind in a humid environment.
