    Lighting cycle timings.

    My main tank lights are on from 1pm - 10pm with actinic from 9.30pm - 12.00am. Up until this weekend, my scrubber lights have been turning off at 9am and turning on again at 3pm, giving the whole tank and sump 4 hours with no lighting (except daylight). I have acquired a new scrubber this weekend and I thought of changing the changing the scrubber light cycle. The scrubber lights now go off at 2.30pm and turn on again at 8.30pm. My theory is that the scrubber is competing against the halide while it is on, so will be working much better when no other lighting is on in the tank (does this make sense?). Am I right in my thinking or am I better with the original timings?

    Thanks

    It actually won't make any difference. The other factors of building/running the scrubber are more important.

    But in general, scrubber growth is best in low nutrients, which is why they grow better after some nutrients have been removed.
