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.
Acidity (low pH) Issues. Acidity is the quantitative capacity of a water or solution to neutralize an alkali. In laymanâs terms that means pH is a measure of the acidity or basicity of an aqueous solution. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. When pH is low, your household plumbing pipes may leach copper into the water causing green stains on bathroom sinks and porcelain surfaces. The water itself may also appear to have a blue-green tint.
