Why does my skimmer go berzerk ???

[MitchM]

I don't think it's the skimmer.

If you have a look at episode 88 pt 4 of LA Fishguys, shortly after they add some skimmate to a new skimmer in a tank with water only, the skimmer foam level starts rising.

Here's a link to the video: http://www.lafishguys.com/88-%20prot...skimmer-04.htm

I think that what's happening in a tank that is otherwise stable with a properly adjusted and clean skimmer and the skimmer suddenly overflows is that there has been a sudden increase in coral allelopathy with increased mucus production.

I don't think you can prepare for it, other than have an in sump skimmer or install a drain tube in your collection cup (part way up the cup) that flows back into your sump.
That way it won't drain your tank and when you notice it just clean your skimmer cup and change your carbon.
