well that is a sad sight. i think you need to figure your ph issue out. if you used a couple tables spoons of vinegar to like a gallon? that is waaaay too much. i use about 4 or 5 drops in a gallon to get mine down from close to 8 to around 6.5. they dont like ph swings at all. i use wood ash(from like a fireplace and only the white ash) to make that water more alkaline if i over do it with the vinegar. wood ash works like vinegar it doesnt take much.
