Application
Ponds need approximately 25kg of Aquaplancton for every 50 sqm but lakes need less, usually a pallet per acre (40 bags) which can be spread from a small boat or poured in front of the propeller of an outboard motor. Large lakes are a lot more stable than small ponds so therefore one treatment is usually sufficient.
You only need to apply the initial dose once. This will then be active for at least a year, sometimes several years. The activity doesn’t suddenly stop, but it does begin to slow down. So, if you are happy with the result and you don’t want it to get back to the way that it was, you can give it a smaller top-up dose, about 1/3 of the initial dose at the end of the year or the following spring, just to keep the whole process ticking over.
