Review on Litmus Universal Indicator Strips Aquarium by Marco Roberson
Extremely inaccurate - do not buy this
. I bought this pH paper because it has generally good reviews. But it's clear that most people don't verify the accuracy of color matching results against known reference standards. Here are two checks I did and the wildly inaccurate results I got from this pH paper: 1) Coca Cola: actual pH 2.3, this article says 5.02) Clorox and distilled water solution : actual pH around 12, this article says 7.0 These errors are HUGE! It's better not to know pH than getting such terribly inaccurate results. Don't waste your time and money on this pathetic product.
