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 PhosExPond)

PhosEx Direct is easy to use
Determine the required quantity. Mix with pond water in a watering can and spread it evenly over the pond. Use preventatively every six weeks and after each algae combat. Do not pour on floating water lily leaves. Do not bathe in swimming ponds for 24 hours after use.

Dosage 40 ml per approx. 800 l pond water.

How high is the binding capacity of 500 ml PhosExPond Direct?

500 ml JBL PhosExPond Direct adsorbs up to 22,500 mg phosphate.

An application of AlgoPond Direct has killed the algae, but they are still on the stones.

This can happen with very firmly fixed thread algae. After the algae treatment we recommend SediEx Pond to mineralize the organic matter.

AlgoPond Direct used near invertebrates and sturgeons

The application of AlgoPond Direct can cause problems for crustaceans in the garden pond, as has been proven in one case.

Here is a biological explanation: Crustaceans have so called external gills. These are situated between the body wall and the external armour, the so-called carapace, which goes left and right along the breast right down to the biramous legs.

The crustaceans use their mouth parts (the so-called exopodites at the mouth parts) to produce a water jet through the front of the gill cavity. While producing this water jet the crustaceans are using their mouth parts to look for food. Therefore it can be possible that particles of AlgoPond Direct granulate reach the gill cavity. Because the active substance in a non-dissolved phase is an irritant, a damage of the lamellas of the gills is possible.

For this to happen, however, that the crustaceans have to ingest non-dissolved AlgoPond Direct in their gill cavity.

With sturgeons no case of a problem with AlgoPond Direct is known. But for the sake of completeness it should be noted that a similar incidence is theoretically possible.

Similar considerations apply for OxyPond and the first component of SediEx Pond. Up till now no cases have been recorded.

I have used AlgoPond Direct but there are still thread algae.

AlgoPond Direct acts always against thread algae through direct contact with them and by releasing active oxygen. However, it is not always possible to reach down deep enough with very dense and thick thread algae pads. Here we recommend either repeated treatment (is now included in the instructions), or a mechanical thinning of the thread algae.

Can JBL PhosEx Pond Direct be used in stainless steel tubs?

JBL PhosEx Pond Direct attacks inferior stainless steels. Because an assessment of the used steels without technical data sheets is not possible, we recommend not using JBL PhosEx Pond Direct in stainless steel tubs.

Averting algae next year – take action now

You may well have asked yourself this year why algae suddenly appear in spring even though you have barely fed your fish yet. It was still cold and the sun had only just begun to shine a little stronger. The reason for it is last year’s “waste” still lying on the bottom of the pond.
