Step 8 - Diagnosing your Koi Problems

Back on the net to see what is wrong with your Koi. Investigation will show that a Koi needs depth to exercise its muscles correctly. The rugby ball shaped body is simply a reaction to being in water that is too shallow. You also notice that the larger fish are swimming at the surface looking like they are gasping for air and they are looking very unhappy. Why is this?

Dissolved Oxygen in Water (DO2)

Dissolved oxygen in water has what they call a different saturation point as the temperature changes. Warm water cannot sustain as high a level of dissolved oxygen as cold water. As a result, the larger fish that need more oxygen start to lag and some may die in hot conditions. Back onto the net again to find out what is wrong, both with the shape of the fish and the gasping. Shock horror! The pond water needs aeration to include more dissolved oxygen and even worse, the pond is too small! In the short term you race to an aquatic centre to buy a pond aerator and an air stone to sustain the fish. Inclusion of this is phenomenal and within no time the fish look happy. Although not the best way to include air into your pond, this solution does help restore a balance for the time being.
