Product information

Clean pond water – optimal water quality
Water cloudiness can be caused by algae, fish excrements or other wastes. JBL’s trouble shooters have been specially created for all types of water cloudiness and treat the pond water without any harmful side effects for the dwellers

JBL’s zero-risk concept
Algae can pollute the pond water and thus cause damage to the fish and the plants in the pond. In collaboration with scientists JBL has developed a concept for a permanent removal of algae.

“1-2-3 algae-free”
Stabilise the water: increase the mineral content for anti-algae agents (JBL StabiloPond) to work more effectively
Combat algae: add a suitable anti-algae agent (JBL AlgoPond) into the water
Limit nutrients: remove the nutrients of dying algae (JBL PhosEx Pond)

PhosEx Pond Filter is easy to use
Fill net bag with granules and rinse it under running water. Insert the net bag between the filter materials of the pond filter or into the special filter media chamber.

FAQ
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.

How high is the binding capacity of 500 g PhosExPond Filter?

500 g JBL PhosExPond Filter adsorb up to 25,000 mg phosphate.

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.

Can the pond care products StabiloPond Basis, JBL StabiloPond KH, JBL OxyPond, JBL FilterStart Pond, JBL PhosEx Pond Filter, JBL SediEx Pond, JBL AlgoPond Sorb, JBL AgoPond Forte*, JBL AlgoPond Green*, JBL PhosEx Pond Direct, JBL BactoPond be used with an operating UV-C water clarifier without any problems or should the UV-C unit be switched off?

In simple terms we can say that when applying the liquid products JBL AlgoPond Sorb, JBL AgoPond Forte*, JBL AlgoPond Green*, JBL PhosEx Pond Direct, JBL BactoPond the UV-C water clarifier should be temporarily switched off so that the active substances will not be destroyed. Please look up the time periods in the respective operation instructions.

With JBL StabiloPond Basis, JBL StabiloPond KH, JBL OxyPond, JBL FilterStart Pond, JBL PhosEx Pond Filter, JBL SediEx Pond the UV-C water clarifier may remain in operation.

* Labelling according to EU Directive 98/8/EC: Use biocides safely. Always read the label and product information before use!

There is no phosphate in the water. Why should I use JBL PhosEx Pond Filter?

Phosphate is the limiting substance to control the algae growth in the garden pond. The value should be under 0.05 mg/l. In limnology (freshwater science) values of 0.035 mg/l are given.
Many tests for phosphate don’t dissolve or don’t dissolve sufficiently in this measuring range.
Also if phosphate can’t be detected with those tests, it gets constantly over fish food, plant remains or material entry through wind into the garden pond. If there are algae the phosphate is mainly bound in them and cannot be detected. For the permanent limitation of the phosphate content the application of JBL PhosEx Pond filter is useful.
