In a small pond or container pond you should be adding the 10ml measure of Barley-Bio Algae Control weekly now to control the green water in this warm weather. If the algae persists you should increase the dose frequency and not the size of each dose.
You cannot overdose Barley-Bio Algae Control as it is not a chemical - so do not worry that you may be adding too much if you do not know the volume of water in your pond. It will do no harm to fish, plants, pets or wildlife.
Plants will work together with your weekly dose of the Barley-Bio Algae Control to maintain a balanced water ecosystem.
To help your small pond or container pond check:
- you have enough rafting plants or waterlily leaves across the surface to give shade to the water that will help keep it cool.
- there are enough healthy submerged oxygenating plants in the pond. These use surplus nutrients that will otherwise be absorbed by the algae and encourage its growth.
