Snail spawn and a skimmer

[asylumdown]

hmmmm, so then it's got to be something else. It's really very quite annoying. I'd put the drain line for the cup right in to the drain that's right next to the sump but I have visions of the skimmer going nuts for long enough to drop the salinity in the tank if I do that. It happened once before in the early days of my tank and I lost 80% of my corals.

Can you think of anything else that would make a skimmer spontaneously go crazy like that?

I dose the standard three - baking soda, calcium chloride, and magnesium via an auto-doser. I just started dosing a a half dose of amino acids, but the first time it did this was before the AA, and the aminos have been going in on nights when the skimmer has not gone crazy. I've been dosing MB7 for the better part of a month now, but I always turn the skimmer off for 4 hours following a dose and it comes back on and goes back to normal almost immediately.
