For the fun of it i thought i would use ringwood. after extensive reading and understanding that this type like oxygen. i decide to cover my carboy with 2 plys of hop bag held in place with a rubber band thinking it might help with some air flow. i place the fermenter in my trough style swamp cooler and through the course of the night i would go check it. so just before bed time i go and have one last only to find it tipped over and completely submerged in bleach water /facepalm. from what i can tell maybe a qt got in because my vol isnt much higher then i put in originally and there no wort in my swamp cooler. needless to say this morning when i woke it was fermenting like crazy lol
