    I have been wanting to clean the skylight over my tank for a while now as I know it is affected by dust, and no rain for four months or so. Also the light in my tank at midday is a little yellower than before.

    I cleaned it and at midday say a huge difference in the whiteness of the light, much whiter and crisper.

    I did a test on another sky light that I could do a proper comparitive test on.

    Before cleaning par level 870.
    After 1490

    71% increase in light.

    Corals are going to love me once they get over the shock.:)

    Remember to clean your lights, it's far more important than you think. Don't waste your electricity and bulbs.

    Bob, with the sudden brightness coming through after a wipe after a long period of time, did you notice any tissue burn on your SPS dude?

    Bob, my outside set-up is the same. I get my garden boy to spray the polycarb roof with a high pressure hose every Saturday. There is a noticeable difference before and after.

    Hmm, interesting. I'm going to pick up a PAR meter in the states soon. Just in time for summer.

    Yup, good idea.

    I really can't see anyone doing a decent job with a greenhouse without one.

    I'll tell you if I do.

    But I don't think so, they only get that max sun for 3-4 hours a day.
