Water regulation in Goldfish
Circulation is more than just oxygen
A by-product of respiration is carbon dioxide, in excess this is dangerous to your Goldfish. When water is circulated by way of a pumps the carbon dioxide is carried to the surface and out of the water into the atmosphere.
Other potentially harmful gases are likewise dissipated into the air by means of water circulation.
Unless water is moving, it will tend to form layers at differing temperatures, where as moving water has one overall temperature.
Circulation is also vital to removing unwanted by-products of the goldfish metabolism, and this includes excess Oxygen which the circulation carries around the pond or aquarium for the benefit of the other fish.
Putting oxygen in and taking harmful substances out can also be done by using the filter return water hose.By placing the hose on the bottom of the pond, this pushes the bottom and middle layers of water to the surface, to recharge the oxygen and maintain a constant temperature within the pond.
Regular partial changes of the water in an aquarium or pond are essential. If you use tap water use water ager
Testing water parameters alerts you to maintenance issues such as pH, Ammonia, Nitrite, Nitrate.
