How to apply: AlgoClear is usually applied using a low pressure garden spray or knapsack. A watering can with a fine rose is also suitable, but it is more difficult to control the application rate. A roller or a brush is also optional.
Dilute shortly before application, using clear tap water or from a water butt.
When to apply: Any time of the year, except during a cold spell. AlgoClear will become less active when temperatures are under 10o. The area should stay wet as long as possible, so it is best avoiding spraying in the full summer sun. The substrate can be moist, but not drenched before applying. If it rains within a few hours, the active ingredient may not have sufficient time to have a full effect.
Application rates: The recommended dilution is one litre of AlgoClear to 14 litres of water in normal, clement weather conditions. In early or late winter, if the prevailing conditions deteriorate a small increase in concentration is a sensible step towards the full efficacy : One part of AlgoClear to 12 parts of water. For light algae contamination, one litre of AlgoClear to 17 litres of water or 14 in inclement weather.
Before applying: If the area to be treated has large lumps of moss, it is best to rake them first to ensure that the substrate itself is well saturated everywhere.
After applying: Leave to dry. There is no smell or smear. The weather will disperse the dead material naturally. Dead algae leaves a characteristic white temporary discoloration.
Effects on plants: Normal wind spray spill should not affect plants. Heavier contact may induce a temporary discoloration of the leaves, but we have no report of other damage on plants.
On Thatch: Test an area first, not all growth on thatch is moss. Iron oxide from the mesh may deactivate the product.
