Customer Comments:

    ...The books [Freshwater Aquarium Chemistry & Freshwater Test Kit Review] were exactly what I was looking for.  I've read them both through a couple of times and taken notes.  I expect to read them several times more.  They are great.  Let me know if you develop any new books.  Thanks for your prompt and courteous service ... and for great products....

    ...I have been interested in freshwater aquariums for about 30 years and have almost always maintained at least one in those 30 years.  I enjoyed your book [Freshwater Aquarium Chemistry], learned a few things from it, and was asking if you had written any other books... You are absolutely correct...there is nobody to ask and no books on the subject....( I have already recommended it to a friend)....
