Fight filamentous algae in the garden pond
Did you know that the advent of annoying filamentous algae in garden ponds is even increased by using chemical means of destruction instead of reducing it? So save yourself the money, because the unpleasant green plague on the water, you get even with simple means soon under control again.
They annoy the garden pond owners especially in summery temperatures, because if the water heats up strongly, the thread algae provide a visible green carpet on the pond surface a few days later. And that should be regular be fished with a rake, because otherwise forms on the pond bottom too high a proportion of digested sludge. The algae can be used after drying as a mulch, which is placed around shrubs and trees or you dispose of the remnants of species on your compost.
Do algae killers help the microcosm in the pond?
Algae deprive the pond flora of important nutrients, especially the phosphates, which are urgently needed by the higher water plants. If you use chemical algae killers now, the algae will die, but the excess of dissolved phosphorus remains on the bottom of the pond, so there is an oversupply that will soon cause another algal bloom. In addition, the thread algae can adapt exceptionally well to their environment and from year to year more resistant to such remedies become.
Consistent removal of nutrients helps against thread algae
It is therefore important to stop the nutrient cycle for the algae, for example, by regularly cutting back your aquatic plants in the garden pond, if possible without leaving residues of this cut waste in the pond water. Also, the sludge is better at least once a year removed from the pond, which is quite easy, but with regard to the possibly existing fish, can do with a mud sucker.
How to prevent new thread algae in the garden pond
Tips
To fill up your pond, instead of using water from the line (often with phosphates to protect the water pipes!), Use the much nutrient-poor rainwater.
