Fast-growing aquatic plants use a lot of nutrients. These are no longer available to the algae. Below I have put together some plants that grow fast. Not all are hardy, so they must be taken out of the pond and wintered in the aquarium. Water lilies, which are so popular with ponds, are not among the crops that are important for the pond's biological balance. They are just beautiful, but that's also a plus. Another advantage of aquatic plants is that they shade the water, especially, of course, floating plants and high marginal plants that provide shade.
  • Hornblatt (hornwort)
  • waterweed
  • basic Essel
  • Crab Claw
  • Brazilian millennium
  • mare's tail
  • Mexican oak leaf
  • Small duckweed
  • Water hyacinth
  • floating rice
  • Waterlily marsilea quadrifolia
  • Muschelblume
  • Büschelfarn
  • European frog bite
  • Floating spurge
Tip: Ideal is the combination of fast-growing aquatic plants and water changes. So many algae are removed. The rest are taken care of by algae-eating fish and invertebrates.

Reduce nutrients

String algae can be starved. You have to extract the nutrients from them. You have different options.
1. Shadow the water surface, at least one third
  • Over and underwater plants
  • awning
The plants not only provide shade, they also provide oxygen in the water. In addition, they consume nutrients, mainly phosphate and nitrate. Water hyacinths are ideal for water purification.
2. Phosphate binding
Algae growth stops when there is not enough phosphate left. Unfortunately, they are very low in value. Especially a lot of phosphate is often in well water. It is therefore recommended to have well water tested. To bind phosphate there are special phosphate binders. These work for about two months, so that the algae only little food left. You need a fair amount. Successes set in about two weeks, because so long to survive thread algae without food. It is best to use the phosphate binder in the filter from autumn until spring. During this time, the pond plants do not grow and do not absorb food.


Tip: There are different phosphate binders, not all are natural.
3. Bacteria
Certain bacteria are able to metabolize the nutrients phosphate and nitrate, making them usable for other organisms. If the conditions are correct overall, the algae can be starved. The bacterial mixture Ema lactic acid bacteria from Emiko was tested. In addition, a suitable sugarcane molasses nutrient solution was used.
The bacterial mixture is propagated according to instructions and is ready for use after 7 days. You can simply pour the liquid into the water or filter. The bacteria activate biodegradation. Decisive are appropriate temperatures, around the 20° C they must lie, not too warm, not too cold. The nice thing is that the bacteria are completely harmless to humans, animals and plants. It is important that enough oxygen is available, because the bacteria consume much of it at work.
4. Algae powder
Even with the algae powders there are differences. A natural means is e.g. Salicylic acid-based. The remedy must be applied about twice a month. It extracts the nutrients from the water. Overdose is not harmful.
Do not use algae powder with copper sulphate. This can cause long-term damage in the water, even if the packaging says: "... harmless to animals and plants".
5. Regular pond care
For pond maintenance, for example, the foliage that lands on the surface of the water is quickly fished in autumn so that it can not sink to the ground. It decomposes and releases a lot of nutrients, which are then available to the algae in the spring. It is best to stretch a net over the pond, which prevents the leaves from getting in.
In addition, dead plant remains of pond plants must be removed regularly. This concerns the plants in and around the pond. Even dead animals provide plenty of nutrients, so remove as soon as possible.

Prevent Nutrient Entry - Prevent

Prevention is better than cure. First, not so many nutrients should get into the pond. This can not be completely avoided, but in terms of quantity, the measures are all-round.
  • Already at the planning on the location of the pond pay attention. There should be no deciduous trees or bushes in the immediate vicinity, even if they are good shade donors. Instead, select evergreens or artificially shade, e.g. with awning
  • Create a pond so that rain can not flush any soil into the pond
  • Do not use soil in the pond, preferably no pond. Simply place plants between stones, pebbles or similar.
  • Many floating plants also shade the pond well and grow without any substrate, they only swim on the water surface
  • Still plant a lot of plants for the water edge, they improve the water quality immensely, are food competitors of the algae
  • Remove dead plants regularly
  • Without fish stocking, the biological balance is much easier to maintain
  • If fish in the pond, then only a few
  • Fish leaves regularly. It must not sink to the bottom where it rots and releases nutrients. It is best to cover the pond with a net in autumn.
  • Scavenger dead algae, their decomposition again produces lots of nutrients
  • Install pond filter
Algae are something natural. An algae-free pond or an algae-free aquarium, however, are not natural. It is important to find the golden mean. Probably nobody has anything against a certain number of filamentous algae; they should not multiply massively. Although it is easier to pour some kind of remedy into the pond than to fish algae and change the water frequently, but of course you can not keep the pond or aquarium clean.
A basic requirement for finding out why too many algae populate the water is accurate water analysis. This must be done in a suitable laboratory. There you also often get tips, which has to be improved and how it can be done easily.
Those who are strongly involved in the cycle of nature need not be surprised when the natural balance tilts. Unfortunately, many fish and plant-friendly remedies for algae are not. Many users had to make this painful experience, others will do it. Of course, providing clean water is safer, albeit more labor intensive. Many plants in the water, little fish stock, do not feed much, fish algae and change water, more is not necessary in most cases.
