Why does the condition of an aquarium deteriorate if the water temperature rises?
A large amount of oxygen needs to be dissolved in water for the microorganisms supporting the environment in the aquarium to be active. However, the amount of dissolved oxygen is reduced as the water temperature rises. Although dissolved oxygen increases by the photosynthesis of aquatic plants, the rate of photosynthesis slows down in an environment where the water temperature exceeds 30°C. Therefore, attention should be paid to any rise in water temperature which may cause deterioration in the aquarium condition. Rise in a water temperature has various harmful effects.
