Description

Algae Klear Xtra is a pond algae treatment that kills algae and blanket weed for good, within 2 weeks. The unique formula targets the algae directly and kills it down to the root to prevent regrowth and improve oxygen levels in ponds. As well as an effective formula, Algae Klear Xtra also contains a UV light filter to reduce the strength of UV rays and therefore, new algae growth.

Algae Klear Xtra works on algae that is submerged below the surface of the water and is attached to the pond walls, pumps and plants. If your algae is floating on the surface of the water, Blanketweed Klear will be required. If you are unsure which algae you have, you can read our Ultimate Guide To Blanket Weed.

Use Algae Klear Xtra as a pond algae treatment to kill existing algae. To prevent algae, the best method is to use a bacterial product such as Pond Klear to reduce excess nutrients in the water that feed algae. It is also important to maintain a stable pH which can be achieved by using Pond Equaliser.
