PH Test for Marine aquarium (7,6 - 9,0). The pH-value or acid value indicates how acidic or alkaline water is. It is a measure of the concentration of the acidic or alkaline components in a hydrous solution. Pure water will react neutral and has a pH-value of 7. If the acidic components are predominant, the pH value will drop below 7. If the basic components predominate, the pH value will rise above 7.

In sea water aquariums the optimum pH value is between 8.2 and 8.5 . Many organisms will react with high sensitivity to large variations of the pH-value An overly large drop or rise should be avoided whenever possible. Therefore a regular check of the pH-level is elementary necessary to note and to avoid any negative development. The pH-reagent from ELOS especially developed for marine aquarium allows the determination of the pH-value with the help of a finely tuned colour scale which shows a range of 7.6 – 9,0 pH-units. • Precise, thanks to the calibrated droplet • Simple to use • Equipped with precision colour chart, measuring vial and syringe • Practical thanks to the easy-opening pack
