Can I use several anti-algae agents together in the pond?

>Each JBL anti-algae agent has a special purpose. It is therefore not necessary to use several AlgoPond products at the same time. Use AlgoPond Green to combat green water. Use AlgoPond forte for thread algae and all other types of algae. If you want to change the product, allow a time interval of 14 days, a water change of at least 50 % and filtering via activated carbon. The products StabiloPond and PhosEx may, of course, be used together with an AlgoPond algae agent according to the 1-2-3 algae-free principle.

 What is JBL AlgoPond Sorb for? When should I use it?

> JBL AlgoPond Sorb is like a pair of sunglasses for the garden pond. The humic substances contained there turn the water slightly amber and thus reduce the amount of light entering the pond. Caring substances like Aloe Vera promote the well-being of the fish. One dosage starting in early spring (from the end of February, depending on weather conditions) and repeated every 4 weeks largely prevents the growth of algae.


I have successfully combatted the algae, but they have come back. Why have they returned and how can I prevent it?

> The main cause of algae in garden ponds is too much light and too many nutrients. When combatting the algae, the nutrients bound in them are released, but then during the next spell of fine weather with sufficient light these nutrients are in the pond again ready to feed the next algae attack.

Preventive measure: JBL PhosExPond direct precipitates phosphates, they are removed from the water and from the algae. JBL PhosExPond filter permanently binds phosphates and limits their value. Having dealt with the algae JBL BactoPond can then be applied to minimize the nitrigen compounds. JBL SediExPond helps reduce the sludge at the bottom of the pond with its heterotrophic (all eating) strains of bacteria.

JBL AlgoPond Sorb adds natural humic substances to the water and through its slight amber colouring reduces the excessive amount of light entering the garden pond. This in turn results in a significant reduction of algae growth.
