I purchased Bislery 20 liters.After opening the cap I found BLACK COLOURED fungi substance floating on the top water surface .Also, few living insects / micro creatures /micro organisim active in the water. The bottle is still lying with me and I require action against the manufacturer.We have always Trusted bislery but these people are selling such substandard quality of water which will detoriate the health of the mass.Water is so precious in life and this is definitely bleach of trust. How such quality is being passed by the certifying authorities.
