Hi David, You were lucky you didn't have any deaths from the co2 dumping. My feline also knocked over a CO2 bottle one night. I walked over to my 75 gal tank the next morning and saw my beautiful school of Congo tetras all floating at the top of the water dead. Lousy way to start a day. I would recommend you get that that stuff out of your tank and back where it belongs- in the bottles. Ray
