My Aquarium Medications article has been updated with a new section;
I added a section about the removal of carbon during treatments, but
more importantly a section dealing with the plethora of false
information from sites such as Yahoo Answers about expiration dates
on
medications (I also am getting really ridiculous emails and even a
PayPal claim based on this false information!)
