As a general rule, match the UV steriliser's rating to your pond's total volume and flow rate — an undersized unit will struggle against algae in a large or heavily stocked pond, while an oversized one is simply wasted running cost. Most units are designed to sit inline with your existing filter system , so the water passing through gets treated continuously rather than in one go. It's also worth checking the bulb's expected lifespan before you buy, as UV output weakens over time even if the light still appears to be on, and a dimming bulb means less effective clarifying power even during peak algae season in summer.
