Alkalinity

The quantitative capacity of water to neutralize an acid; that is, the measure of how much acid can be added to a liquid without causing a significant change in pH.

Ammonia

Where does the ammonia originate from?

Chlorine

Acceptable concentration 0 A gas widely used in the disinfection of water and as an oxidizing agent for organic matter, manganese, iron, and hydrogen sulfide.

Green Water - Algae

Sometimes referred to as an algae bloom, Another factor which can influence the pH of the water is the presence of plants, most notably if there is an algae bloom in the pond. During the hours of daylight, plants produce nutrients directly from car

Nitrate

Nitrate, NO3-N, Nitrate is the final product from the breakdown of ammonia released by the fish.

pH

The pH is in all respects a measure of acidity and alkalinity, pH 0 - 6.99 is acid; pH 7.0 is regarded as neutral and pH 7.01 - 14.0 is alkaline. On the whole the pH is not generally a problem but it can have a profound effect on the toxicity of ammo

Salinity

Common salt, Sodium Chloride (NaCl) is commonly used in the health care and maintenance of fishes especially Koi. Salt is useful in treating parasites. It will eliminate seven out of nine parasites that are commonly found in Koi pond.

Water change outs

Partial water change outs can reduce the amount of anything dissolved in the water but not totally remove it. Although it is sometimes necessary, draining and refilling a pond should only be used as a last resort!
