Oase AquaActiv AlGo Direct Blanketweed Control 500ml

The ABC of algae control.

AlGo Direct - removes string algae quickly and reliably by releasing active oxygen. The algae are killed off in the shortest imagineable time and can then be removed using a pond net. Any remaining algae are biologically decomposed by the action of the microorganisms.

Only use if the pH value is between 6.5 and 8.5 (6in1 QuickStick) and the KH value is above 3o dH. Immerse the test strips provided for approx. one second, shake lightly and read after one minute. At KH < 3o dH (e.g. rainwater), harden first with OptiPond. Remove as much algae as possible prior to application and then evenly scatter 50 to 100ml per m2 of treated surface over the algae nests. Do not sprinkle on aquatic plants. Allow to take effect for 1 to 2 hours. Repeat dosage if algae start to grow again, but wait at least three days. Observe a safety interval of at least 12 hours in swimming ponds. Dilute the product residues with water and dispose of in the drainage system. Do not reuse empty packaging. Store in a dry location. Use biocides safely. Always read the label and product information before use.

500ml treats up to 10000L of water

  • Combats stubborn string algae
