I have a big batch of Red Grape Caulerpa. My kid wants to do a Jr High science project with it. So here are a couple ideas and questions. She wants to base her study on either light, or nutrients. So, start with the hypothesis, weigh out 4 samples of algae. Set them up in four mason jars with a bubbler, using tank water from a water change. Apply different lights, or add different nutrients to each. After a period of time, remove the samples and weigh them again to quantify growth. No test kits can be used. No animals can be used.
My questions are:
My questions are:
- How much time would we need to show significant growth?
- What lighting options are there to isolate red, blue, full spectrum, and zero light?
- Or, what nutrients and how do I add them without using fish or bacterial biome?
