Compatibility Notes

When shopping for a replacement, it is crucial to match the pin layout of your existing fixture. Laguna utilizes two distinct styles of 25W bulbs across their filtration lineups:
  1. The PT1656 / PT1655 / PT1658 (PowerClear Max 2000): This uses a double-ended, 2-pin (G13) straight tube.
Maintenance Tips

  • Replace annually: Even if the bulb still glows, UV-C bulbs lose their biological effectiveness over time. Pond experts recommend replacing them at the beginning of each pond season.
  • Clean the quartz sleeve: While replacing the bulb, always inspect and wipe down the glass quartz sleeve surrounding it. Algae and mineral buildup on the sleeve block the UV light from penetrating the water.
  • Safety warning: Never look directly at an active UV-C bulb, as it can cause serious, permanent damage to your eyes and skin.
