The Laguna Pressure Flo Filter is super effective and great for keeping your pond in teh best condition, but the UVC bulb will need replacing every 6 - 12 months to ensure it can carry on at the optimum level. You can find hte Laguna UVC tubes here at Swell UK, available in an 11w PLS, and 18w and 24w PLL fittings.
The 11w PLS comes with a two-pin connection, and is the replacement for the 3000 and 6000 models, whilst the PLL bulb is a 4 pin connection, with the 18w replacement for 10000, and 24w for 14000.
