If you have a pond and want to keep Koi or other fishes you need a pond aerator of some sorts.
The applications for aeration are numerous and the following are only a few examples where increased oxygen can be beneficial. Ponds can benefit greatly from increased oxygen levels in controlling algae, bacteria, fungi and molds. When an aeration system is properly applied, the overall health of the pond will be enhanced. Fish will grow faster and stay healthy. In addition, the water movement will keep the pond from freezing in the winter, thus keeping oxygen-robbing fish and plant life sustained. The freezing of a pond in the winter can be the biggest detriment to pond owners since algae forms on the bottom of the pond during the colder temperatures, and then as the pond turns over in the spring the algae surfaces. Cisterns that store water can utilize oxygen to combat various contaminants and keep the water from becoming stagnant. Oxygen added to water stored for drinking will help deter bacterial growth. Reclamation tanks used in greenhouse flood floors can benefit from higher levels of oxygen. Plants will receive more oxygen to the root zone, which will enhance growth and retard disease.
The performance of both pond heaters and aeration systems vary depending on how cold it gets in your area. Even when vented properly, layers of ice appear may over when temperatures dip well below freezing. If this only occurs temporarily, and is short in duration while the coldest temperatures and wind are present, there should not be any cause for concern, as a calm or sunny day will give the pond the help it needs to re-open the hole in the ice. If it is necessary to manually reopen the air vent do not try to break through it by hitting it with hammers or heavy objects as this creates vibrations that can harm your fish. If necessary pour a bucket of warm water over the vent hole to melt it back open.

Without proper aeration, ponds begin a negative, counter-productive cycle. The pond will become eutrophic and begin to produce algae, which may also cause foul odors. Without oxygen, accumulation of fish waste, dead vegetation and other organic material becomes a black muck resting on the bottom of the pond which then releases nutrients that feed pond algae and pond vegetation. Windmill Aeration is an economic, safe, low maintenance and attractive option to reduce sediment and help decompose all organic materials in your pond. Also, it will eliminate thermal stratification, prevent fish kills, creating a stronger and more productive population, and overall, a healthier . Aerating your pond will also prevent stratification from occurring during the winter months. Stratification is when a layering of cooler, heavier layer stays on the bottom, while a warmer, lighter layer sits on the top. In cooler months, the air will cool the warmer top layer and causes these layers to mix. The bottom layer is dead and toxic, and when it mixes with the healthier top layer causes a "turnover", which adds stress to the fish, increases the mortality and causing a "fish kill". Based on the geographical region, fish pond located away from power lines. So, it is necessary to use local potentials of renewable energy such as solar energy. The annual average solar radiation in Indonesia is 4.5 kWh/m2/day with 9% monthly variation. The main objective of the present study is to design the optimum sizing of electric power design to support the electricity demand of fish pond aeration system. Applied methodology provides a simple approach for sizing electricity system using HOMER software (Hybrid Optimization Model for Electric Renewables) to fulfill the requirement of 450 Wh/day primary load with 1.692 Wh/day peak load. The result of the analysis is a list of feasible configuration power system sorted according to the cost of energy (COE). The result show the optimal sizing of photovoltaic 1 kW, 8 battery of 200 Ah and inverter 0,2 kW. This is the most economically feasible and least cost of energy (COE) is about 0,769 $/kWh.
