Acidity/Alkalinity and pH levels in Ponds. pH stands for Potential Hydrogen. The scale is from 1 to 14 with 1 being acid, 14 being alkaline and 7 being neutral. It is a measure of whether the water in your pond is on the acid side or on the alkaline side. The blood of fish is 7.4, so an ideal pH for your pond would be 7.4.

ponds • A pond can vary in many ways, one of which is how acid or alkali the water is. This can be due to the type of soil or rock the pond is on, how much carbon dioxide is in the air, acid rain or even the type of plants present. • A high pH (alkaline conditions) favours some species while low pH (acid conditions) favours other species.
