    Hi eveyone. Quick q: how do you know when your laser bulb needs replacing. Mine has literally just stopped working. Its pretty dirty looking. Any other clues?

    Dirty? Got green algae living in the tube? If so then you will need to replace it. The water you run through the tube must be deionised and also have a bit of antifreeze for good measure.

    You can try flushing through with bleach but chances are the tube is toast.

    When a tube dies, it usually makes a fizzing sound like it is losing air, the intensity is dramatically reduced and finally stops working.
