Thank you!
I have the weirdest problem because the uv box was dropped on the ground. The glass sleeve broke and in a weird way some of the glass is stuck in the uv box. The seller in Norway had never heard about such a problem before. Either I have to find a way to get it out or buy a new box and a new glass sleeve.

will the turbine still spin if the lights is off ? and the pump is on ?

What would cause the blue light to flash?

Hi There, Great vid. Are you able to say which make/type of grease/lube did you use for the rubber at the base of the UV cover?...many thanks

Is it normal for the light to flash??
