Ruuning bio-pellets without a skimmer?

not that it matters, but if it were me I would also just leave them as well. That is, if it was just for a couple of days as you say. Beyond that, then yes, definitely take them off line. But it sounds like you've made up your mind anyway. The only concern I would have is that two days without water running through the reactor could stagnate the reactor a bit.
