Correct the pH if it falls below 7.2 or rises above 7.6. Correct pH will ensure the chlorine is working effectively.
The most elementary one is Litmus Paper. It measures red for acid and blue for alkali. Then there is UNIVERSAL INDICATOR, a liquid, This will slowly change colour from red(very acidic (pH 1)) to green(neutrality) (pH 7) to indigo (Alkaline )PH14)) Theren there is a pH meter , which is an electronic probe put into the solution to read off the pH .
pH 7 is best because it is neutral.
pH 9-10
you can use ph when you need it
Catalase works best at a pH of around 7, which is considered neutral.
About 7.4 pH.
the pH scale
Pepsin works best in acidic environments and it's optimal pH (the pH at which it works best) is 2.0
Avicel pH 102 is typically used as a pH buffer in pharmaceutical formulations. It is commonly used in the range of pH 5.5 to 7.5, but the exact pH can vary depending on the specific formulation and conditions.
the best pH for African cichlids is anywhere from 7.5 to 8.5 they like a high blue colour if you have a pH tester.
A pH meter or pH test strips can be used to measure the pH value of a solution. pH meters provide a numerical value of the pH, while pH test strips change color based on the pH level of the solution, allowing for an approximation of the pH value.
A pH over 7 is basic.A pH=7 is neutral.A pH under 7 is acid.
