Dick,

Thanks for your reply. As always, great advice. "I see said the blind man", it never occurred to me to protect the filter for the Q-tank. Besides the aeration of the filter, are there any other requirements to maintain bacteria culture? How long can the culture be maintain under these circumstances?

I'm guessing in the meantime, the Q-tank aerarion and filtration will be from a portable third source? For 1000 gallons, I think this is reasonable equipment to have, I just need to plan the location of the convenience outlets in the right places. Thanks again. Boy is this project getting BIG!
