Some of the water from the culture container spilled (or evaporated) and I want to add more water. Can I just add some tap water?
Never add tap water to a culture. It contains chlorine and in some cases chloramines that are toxic to protozoa, algae, and other living organisms such as fish and tadpoles. Use room temperature springwater instead. We recommend Carolina™ Springwater, which we use to grow many of our organisms. If this is not an option, you can purchase springwater from your local grocery store. Be sure to carefully read the label to ensure there are no additional additives for taste, and that the source is not a municipal water supply. The label should state that the water came from a “natural springwater” source. “What types of microscopes can be used to view live organisms?” For protozoa and algae use a compound microscope for close, detailed viewing. To observe swimming and interactions with other organisms within the culture, use a stereomicroscope. Use a compound microscope with an oil-immersion objective to view bacteria and fungus. “What are the ingredients of Alga-Gro® media?” Alga-Gro® media
