| Q:
Why does your pH test kit read lower than my pH probe and
some of the other test kits on the market?
A: If your reading is way off, check the supplied reference
to make sure the reagents are working. If the reference
doesn’t give you the correct reading, we will replace
the faulty reagent free of charge. If the difference in
pH reading between the Seachem kit and other kits is small
this is mainly due to a difference in the manner in which
our kit determines the pH; the result is a more valid pH
reading from our kit because our compensates for the high
ionic strength of saltwater. If you are using a pH probe,
be sure it is correctly calibrated. Even if it is, pH meters
can sometimes be affected by the high ionic strength of
saltwater tanks.
