no, the bottle was under the tank in the stand. I have no idea how that much liquid traveled up and into the tank.
I couldn't wait it out. I saw this morning that a pleco and a crayfish were also amongst the dead and that my dempsey's mouths were getting clogged with a gooey white film. I took out all the water, rinsed the gravel and suctioned again. The tank does look clear now and if i can reacclimate the dempsey's to it without them bitting the dust i will be happy.
Thanks again for everyones help.
