Hunter's comment
It is very important to maintain the quality of oxygen in the fish pond. If the quality is bad, it will affect the fish. They will die quickly. For this reason, oxygen aeration is needed. It aims to supply oxygen to the pond.
The problem is that the electric-powered aeration system is very expensive.
eO2 + is an oxygen aerator powered by solar power. It's easy to use and maintain. Fish farmers can save their money because they don't depend on electricity anymore.
