Best for
Larger planted tanks where you want UV only for set hours, or want it tied into an Eheim digital setup.
Worth knowing
It costs about twice as much as the standard reeflexUV for the same job, so only worth it if you will use the scheduling.
What stands out
- Constant, daily cycle or coupled modes over WiFi
- Booster mode for a short, intense treatment
- Lamp change reminder by e-mail
- Switches off automatically when you open it to change the lamp
