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 7.00 . If the acidic components are predominant, the pH value will drop below 7.00. If the basic components are predominant, the pH-value will rise about 7.00.

The saltwater aquarium pH-value should be between 8.1 and 8.4 which is the value found in natural seawater.
Many organisms will react with high sensitivity to very small variations of the pH-value. A large drop or rise should be avoided. Most organisms react poorly (or die) with a pH-level, that is constantly far away from the requested value as well as on gravid modifications.
Therefore, a regular check on the pH-level is necessary to note and to avoid any negative development.

ELOS AquaTest pH, as well as all the other colorimetric test kit of this line, grants high accuracy thanks to several procedures. The precision of a colorimetric test kit is, in fact, strictly related to the precision of the color chart. In these test we use “RealColor” technology, an accurate system to calibrate the colors chart compared to the reagents, on each production batch. In combination with the use of NIST (National Institute of Standard and Technology) certified samples, this grants high accuracy and constant test results.

Test kit reagents are very delicate, their accuracy is significantly influenced by storage. For this reason we keep our stock strictly under control and we suggest, to all our retailers, to do the same in order that on the shelves ONLY the most actual and fresh production batch is available. When you purchase a test kit be sure to check the Best Before Date.

ELOS AquaTest pH M shows a range of 8.1 / 9.0 pH-units.


  • Easy reading:RealColor” technology.
  • High precision: thanks to the use of calibrated dropper
  • NIST validation: each batch is validated using NIST (National Institute of Standard and Technology) samples
  • "Safe reagents": reagents and testing procedures are based on Low Risk Reagents. None of our test kit are based on Toxic Reagents.
