In all stagnant water • To stabilize/restore water quality • To precipitate heavy metals • To reduce the toxicity of nitrite • To combat ammonia poisoning of fish. Also approved for use in treating potable water.
The water parameters often change and become instable due to the growth of algae and/or ornamental plants, the fish population, adding water and dead leaves falling into the pond. pH-values that remain above 8.5 and strong fluctuations in the pH-value place a strain on plants and animals. OptiLake improves the water quality, enabling ecological equilibrium to be achieved. OptiLake provides essential calcium and carbon dioxide to quickly create an ideal environment for all fish, plants and pond inhabitants. This buffer ensures a stable pH-value between 7.5 and 8.3 in the pond/biotope, and fluctuations in the pH-value are prevented. An optimal carbon dioxide concentration as well as ideal hydrogen carbonate and calcium contents are imperative to the survival of all living organisms in the pond. OptiLake also supports the growth and reproduction of algaeeating micro-organisms (e.g. daphnia and rotatoria), so biological self-purification of the pond begins immediately! Optimal conditions for micro-organisms that break down toxins are created in the pond and the filters. A positive side effect is that OptiLake reduces the corrosion of pumps and pipes.
Ideal application time
OptiLake can be used at any time of year. Treatment with OptiLake is particularly important in the spring and
summer, when the biological equilibrium is at the greatest risk. When rain water is used in a pond, OptiLake
is essential. Rain water does not have sufficient carbonate hardness, so drastic fluctuations in the pH-value
b) Type of application
Spread OptiLake evenly over the entire surface of the pond without first diluting it in water. The water will
be cloudy for a short time after treatment, but this is normal. Rinse powder residue off of plants. The filters can
remain in operation, and animals can remain in the pond.
100 g OptiLake per 1000 liters (1 m³) of pond water.
An overdose of OptiLake is not possible. However, an insufficient quantity will not produce the desired
effect. In certain cases, a higher dose may be needed: This is the case if, in the early evening the pH-value is
greater than 9.5 and/or the KH-value is less than 3.5 °dH (Rule of thumb: KH greater than 3.3 °dH =
100 g/m³ · KH between 1.6 and 3.3 °dH = 200 g/m³ · KH less than 1.6 °dH = 300 g/m³). Use the
AquaCheck Set, part of the Lavaris Lake pond care program, to determine the pH-value and KH-value. When
the values are known, consult the included table for the required dose.
