A planted pond and fish consume oxygen. If there are many fish in the pond, oxygen must be supplied in any case. A stream, waterfall, water feature or fountain is often sufficient for this. A pond aerator also prevents a lack of oxygen in the pond.

• immediate treatment with Sera Pond Omnisan F
• remove all sharp-edged objects in the pond
• use a UV lamp with sufficient power, as this also kills mold spores
• the use of pond bacteria such as Söll Biobooster (the more pollutants the pond bacteria break down, the fewer pollutants are left for the fungi and the fewer fungal spores form in the water)
• Remove fish from the pond that have become ill due to excessive fungal infestation
• create optimal water values
• Use pond filters from rain barrels or IBC pond filters
• Remove plant debris and leaves from the pond
• aerate the pond well
• Remove parasites that “gnaw” on the mucous membranes of the fish from the pond
• carry out the fish stocking correctly
• Strengthen the defenses of the fish with Söll fish mineral and thus make them more resistant to diseases (especially before winter, since the fungal spores can multiply better at low temperatures)
