Hi I got a tetra pond bio active pond filter which I thought the uv bulb was blown but when I just replaced it the new bulb don't work either? So I am thinking the uv electrical assembly must have gone wrong but its a fixed unit so what do I do now???
Cleaned my pond filter today what a messy job that is. Think I need a new bulb anyone know the best place to buy bulbs on line? My filter is Tetra PFX-UV12000 been told it's a 18 watt bulb but will have a better look tomorrow when I remove old bulb.
