In a marine aquarium the pH measurement is of great importance. Marine aquarists routinely test their seawater pH level, but what is pH? It is not intended to go into great scientific detail but to give a general explanation of the term. For those who want to delve into the scientific world, I’m afraid you’ll have to look elsewhere. I’ll also give a little information on its control.
First of all, pH is a measurement of the acidity or alkalinity of our seawater. The measurements are set against a scale which runs from 0 to 14. The centre of the scale, 7, is neutral. 0 is acid and 14 is alkaline. Out of interest, Sulfuric acid measures 0, and Sodium hydroxide measures 14.Read more →
