Bio and ultra life if used as directed and for the correct period of time is a fantastic 100% natural way of ridding systems of algal issues providing there is no continued underlying cause.
Works well for - outbreaks due to holiday over feeding, reduced water change schedules, accidental nutrient over dosing, cyano outbreaks in a normally healthy system
Does not work so well for established high nutrient issues in established old tanks where the nutrients have become bound in tanks structures. In this case we recommend regular maintenance with bak and bio.
