I have two albino corys, one Julli cory and two emerald corys. They are in a 55 gallon with one pangasius cat, a pearl flowerhorn, a pleco, a banjo cat, and a spotted green puffer. Everyone gets along very well. The corys love to school together and you can tell the albinos are a pair - they are always together.
A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value.
A pH value of 7 is neither acid or alkaline and is considered neutral. Pure water has a pH of 7 and is neutral. The pH scale is based on the hydrogen ions concentration [H+] in the food. The more hydrogen ions present, the more acid the food and the lower the pH.The diagram below shows the pH scale and the taste of foods at acid and alkaline pH values.he more hydrogen ions present, the more acid the food and the lower the pH. The diagram below shows the pH scale and the taste of foods at acid and alkaline pH values.
