Lavaris Lake Pond Maintenance Scheme

NEW POND - Start in Spring


When a new pond is created, we recommend applying 100 g of SeDox for each m3 of pond water (in existing ponds, the dosage is 50 g/m3). This permanently eliminates copper and other metal from the water. SeDox causes phosphate (e.g. in the water or the plant soil) to bond completely and be converted to apatite. This prevents algae from growing quickly, because the nutrients that the algae need are no longer available. However, the phosphates remain accessible as nutrients to the other plants in the form of apatite.



• The phosphate dissolved in the water bonds to form apatite; 100 % bio-compatibility

• Active oxygen due to greatly increased nitrogen decomposition

• Better sludge decomposition

• Purely mineral, no heavy metals or aluminium

• Works for 6 – 8 weeks


To achieve a natural balance between the individual water parameters, 100 g OptiLake should be applied for each m3 of water



• Improves water quality and creates an ideal habitat for the pond population

• Increases carbonate hardness and prevents fluctuations in pH-value

• Helps to prevent excess heavy metals and ammonia poisoning

• Essential when using rain water


Then begin the biological process with ClearLake (water micro-organisms, year round care). ClearLake should be used only when the water is at least 12 °C. The carbonate hardness should always be at least 5° dH and the pH-value between 7.5 and 8.5! If the values are not within these ranges, the natural balance should be restored by applying OptiLake.



• natural bacteria enhance and accelerate the biological self-purification process of the water

• Limits algae bloom and helps to achieve biological equilibrium

• Combats decay and formation of hazardous gas

• Activates the biological decomposition of sunken leaves, dead plants, feed residue, etc.


Prevent Blue-green and other Algae. 

Conventional algae such as suspended algae (water appears green) or thread algae do not look nice, but they are relatively harmless. Blue-green algae (recognized by thick, slimy, shimmering blue-green clumps floating on the pond surface) on the other hand, can produce hazardous substances in the water and often trigger allergies, nausea, rashes and asthma!



• Immediate remedy for stubborn algae formation

• Effectively prevents blue-green algae from blooming and reduces new growth



Destroys excessive filamentous algae with active oxygen. Sprinkle AlgoLon directly onto the filamentous algae. Use in the morning for best results. 




If there is a problem with algae, AlgoClear/AlgoLon and SeDox should be used again as described above.


For thorough oxygenation of the water and sediment as well as to prevent germs and marsh gas (colour and cloudiness),we recommend applying OxyActive.



• Remedies acute oxygen deficiency and regulates the water's oxygen content

• Promotes sustained biological self-purifying capacity


For healthy plants and bright colours,we recommend using AquaFloraEnergen during the entire vegetation period, particularly in a new pond or when lack of oxygen is severe.



• Provides vital plant nutrients and prevents lack of nutrients

• Strengthens and activates plant growth and makes the blossom colours brighter

• Increases the resistance of plants to external factors

• Phosphorous-free


Mid August or later: ClearLake, to ensure urea decomposition




To best prepare the pond for the approaching winter months, we recommend applying SeDox (50 g/m3) in September/ October to bond the phosphate. This will prevent algae blooms, which can happen even during the winter if there are a few sunny days. Also, SeDox releases oxygen in the water and benefits the plants and organisms.


One OptiLake treatment (100 g/m3) should also be administered to stabilize the biological equilibrium and to break down hazardous substances (ammonium, nitrite, heavy metals).
