upside down bottles?
I have noticed in every phytoplankton culture I have ever seen the 2 liter bottles are always right side up... Is there merit to the idea of keeping the bottles upside down with air coming in through the bottlecap to prevent phytos or whatever from settling into the bottle? If the air is all the way at the bottom of the bottle (cap end, when upside down) it seems as though it would work.?? Any thoughts....
