JBL AlgoPond Sorb - 2.5L

JBL AlgoPond Sorb - 2.5L is a pond treatment aimed at algae. JBL describes it as a biological algae blocker for pond water that suits both fish and plants, and sells it in a 2.5 litre container.

Key Features

• For garden ponds: part of JBL's pond range rather than its aquarium range.
• JBL's description: the brand calls it a biological algae blocker, working with the pond rather than against it.
• Suitable with fish and plants: JBL states it is for pond water that has to suit both.
• 2.5 litre container: a pond-scale quantity, so work out your volume before you order.
• Dose by pond volume: length times width times average depth gives you cubic metres, and a cubic metre is a thousand litres.
• Test as you go: phosphate and nitrate readings tell you whether the pond is still feeding its algae.

Algae In A Pond

• Shade helps more than any bottle. Lilies and floating plants covering part of the surface take light away from algae.
• Fast-growing marginal and submerged plants compete for the same nutrients the algae want.
• Net out blanketweed by hand and pull debris off the bottom. Every handful removed is nutrient out of the pond.
• Cut the feeding back. Uneaten pond food is one of the biggest nutrient inputs there is.
• Keep the water moving and aerated, especially in hot weather when it holds less oxygen.

Good To Know

• Work out your pond volume properly before you dose anything. Guessing high wastes product, and guessing low means it does not work.
• Dose in the morning in settled weather, and keep the pump and any aeration running while the product works.
• Store the container closed, off the ground and out of the sun, and keep it away from children and pets.
• Follow the dose rate printed on the container. Ask us if you need the label details before ordering, so you can work out how far it goes in your pond.
• Anything that kills algae leaves dead algae behind, and that uses oxygen as it breaks down. Keep aeration running and remove what you can.
• If the pond has fish, watch them closely for the first day after any treatment.
