Specialized drains are an important consideration. Most species can thrive with 12-16 hours of light per day supplied either naturally or by balanced fluorescent lights. Animal rooms should be equipped with overhead lighting with timer control. Depending upon the protocol, as appropriate photoperiod control is then accomplished either by control of room lighting or by placing timers on individual aquaria, as appropriate. Air intakes for central compressed air is to be filtered and protected from airborne contaminants such as previously mentioned.
Humidity control is to be provided for all areas.
Emergency power must be provided to critical life support systems such as aeration, filtration, and lighting. Loss of power can result in catastrophic losses in just a few hours especially under conditions of increased temperature and high stocking densities. Tank support must be carefully considered in terms of weight distribution and construction materials. Wooden supports are not appropriate. Rooms also need to have a net disinfection system.
