Savio 35W High Output UV Replacement Bulb for Ponds up to 2,500 gal If your Savio SuperNova clarifier was clearing green water reliably and now it's not, the bulb is the first thing to check. UV output degrades gradually over thousands of hours. By the time most bulbs visibly flicker, they've been running below effective output for months. This genuine Savio 35W high-output replacement restores full clarification capacity so your system performs the way it was built to. How UV Clarification Works UV light at the right intensity disrupts the reproductive cycle of single-celled algae, causing suspended cells to clump together. Your filter captures those clumps and pulls them out of the water column. The 35W high-output format delivers enough UV energy to clear green water in medium-sized ponds within 3 to 7 days of installation.
