Questions & Answers

Drs Foster and Smith Articles

The Importance of Regular Testing
As a fish hobbyist, it is imperative that you have an understanding of the water parameters that affect fish health, as well as the importance of water testing. Water testing cues you to what's happening in the system at any given time.
Marine pH Factor
