When an overseas brand has your spare parts stuck on a one-month air freight waitlist, your aquarium systems can’t sit idle. We build custom UV lamps and ship in 7 days, with stock on hand so you can move the same day. What matters, technically Algae control comes down to wavelength and dose. We run at 365nm — the band that gets the photochemical pathways working to knock out algae reproduction. Peak irradiance is tuned to ≥80 mW/cm² at the target plane, which lands you in a delivered dose of 100–200 mJ/cm² across the water column. That window is enough to degrade nucleic acids in microorganisms without driving water temperature past operational limits. We use ozone-free quartz sleeves and high-purity mercury vapor, and the reflector geometry keeps the beam collimated. Output holds within 5% over 5,000 hours. Why it works in the field You get a plug-and-play module built for aquarium duty: IP65 housing, corrosion-resistant fittings, and voltage coverage from 100V to 240V. The footprint is compact enough for tight manifolds, and the connector interface matches up with common industrial fixtures. With a 7-day custom lead time, you avoid long shutdowns. You keep control steady, maintenance predictable, and energy draw lower than you get with broader-spectrum sources. Here’s what to keep straight Installation means matching the lamp to the sleeve, and the sleeve to the reactor’s flow rate. If those don’t line up, effective dose falls off. Check your reactor’s hydraulic profile, and set the lamp orientation to match flow so exposure is uniform. Expect a 5–8°C rise at the sleeve surface under continuous duty. Plan heat dissipation accordingly.
