What are the most common water contaminants? A basic principle in research is to eliminate as many variables as possible during a study. Water quality is an important variable to consider. Many contaminants are found in water such as particles, organics, dissolved ions, pyrogens, bacteria, viruses, and other microorganisms.

Keeping The Lights On

Many animal behaviors are strongly influenced by the amount of ambient light. Lighting is a critical factor in both circadian rhythms and breeding cycles. Knowing the importance of lighting in the vivarium, how do you select the best lighting solution? 

Lighting for vivarium use should be designed for animals and the staff that care for them. Energy efficiency is important, but it is secondary to reliability and verification of lighting. Animals cannot override the lights if the lights are not correct. Vivarium management must ensure proper light cycles for animals under their care and provide evidence that it is working correctly. Reliability means knowing what failures the system can detect and if these failures can be automatically recovered from by the system. Verification of lighting provides data to all parties on the lighting experienced by the animals. Finally, lighting schedules and allowed deviations must be controlled by
