The photosynthetic, living bacteria break down dirt and thus provide crystal clear water in the pond.
These unique PSB bacteria are grown in the Netherlands and poured undiluted in the bottle. They become active as soon as they end up in the water.
Bactoplus Fresh PSB removes ammonia and other pollution and thus improves water quality and clarity.
PSB bacteria do not consume oxygen and can therefore be used in very high doses. The red colour is completely natural, the product does not contain dyes.
100% organic and safe to use, even at high doses.
