So, what’s the lifespan of a seawater disinfection system? It’s like asking how long a goldfish lives—it depends on the size of the bowl and how often you forget to feed it. In a perfect world, 15 years. In a world where you ignore the manual, 3 years and a lot of swearing.
Treat it like a needy but brilliant friend: give it clean power, a weekly rinse, and don’t let it sit in the dark with dead barnacles. Do that, and you’ll get a decade of disinfecting, with a bonus of not accidentally poisoning your fish or your drinking water. Now go hug your UV lamp. It’s working harder than you think.
