The more favorable the location of a pond, the clearer its water will be. Many shade providers and as few deciduous trees as possible in the vicinity help to reduce algae growth and reduce the formation of unwanted biomass on the pond floor, which quickly turns the water in the pool green.
Plants and shade help with water clouded by algae
- in the event of massive algal blooms or the onset of fish death, it is essential to have the current water parameters tested in a laboratory (pH value, carbonate hardness, nitrite & nitrate and ammonium);
- Remove floating algae and duckweed regularly with a net; if necessary, install filter systems with a UV clarifier (especially for ponds with small amounts of water);
- use targeted nutrient competition against algae with suitable pond planting (sedge, sweet flag, milfoil);
- in unfavorable locations, surface skimmers (skimmer) and the use of leaf protection nets over the water basin can reduce large quantities of plant residue deposits on the pond floor and ensure clear water in the garden pond;
- regular checks of the pond contents for water loss (nutrient values otherwise reach a critical concentration);
tips
If pond plants are too deep or too shallow, they wither quickly and thus form an unwanted excess of biomass. Therefore, the plant-specific water depth should be strictly adhered to for each type of plant.
