I just received my August 2018 issue of pme and noted on the cover that it had a bullet indicating “The code for hard water,” which was also the tag under the only feature this month. I have had several projects where hard water was an issue so I was interested to read the article.
I think you did your readers, and to some extent your magazine, a disservice by “selling” this as a feature and that it would focus on “code”. Although it is a useful piece of information, this is much more of an advertorial than an article. You do clearly state that the president of Aqua-Rex is the author of the article, but this company name appears nowhere in the article, and it is not readily apparent that the author of the article is also the president of the company that makes the technology he is talking about. The impact of the article rings a little hollow once this connection is made.
