The Oase AquaActiv Phosless Direct is a pond treatment that is designed to bind one of the key nutrients that algae requires to grow, phosphate, to aid in the prevention of algal blooms. Every 100ml of Phosless Direct binds up to 22g of phosphates, pulling them out of solution safely into a non-bioavailable form.

Not only does this treatment bind phosphates, but also hydrogen sulphide. Hydrogen sulphide is a toxic substance that is produced when anaerobic bacteria break down organic material in ponds with low oxygen levels. Not only is it toxic to fish and other plant life, but it also responsible for the characteristic rotten egg stench around stagnant water.

Before using any pond treatments, we recommend that water tests are carried out using the Oase AquaActiv Profi-Set Water Analysis Kits to determine the key nutrient levels in the pond. This enables a more targeted treatment by only treating the nutrients that are present in excess.
