Copper piping and lead-based solders should be avoided. Rooms should be provided with adequate facility-wide drainage. This requires drains in several locations.

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.
