Feedback for Science Fair Project
My 8th grade daughter wants to use our aquarium in some way for her science fair project. We were thinking it would be interesting to test the effects of various types of fertilizer runoff on the environment. Since we live on the coast and our storm system dumps directly into the ocean it is a relevant topic for her. There was also a recent article in our local newspaper regarding the negative effects of run off in the watershed. We thought we would try a liquid like Miracle Grow, a solid fertilizer, and steer manure. We will put three small bowls in my refiguium and add a measured length of calupera and 5 or 6 cope pods. We would then add a small amount of each fertilizer and monitor the effects. We would also plant some grass in three different containers and add the same fertilizers. The test will be to see if there is any difference in the effects on a marine environment vs. how well the fertilizer helps the grass grow.
Does this seem like a good idea that is likely to produce any results? Also, how should we add the fertilizer and how to we insure the same concentration is added of each type? Will any of the standard reef test kits be useful for this experiment? Any feedback is appreciated. I will post this in the Chemistry Forum as well... Thank You, Kevin Hobby Experience: 8 years reef. |

it sounds like an ok idea, but your tank might crash from the fertilizers

You should use a coral as well. Say a Xenia frag that was attached to a rock for a while. then have them all be about the same size.
To mimic the ocean, the concentrations would be in the PPB or so. So you'd really need to dilute the samples. But you may decide to dilute all of them to several dilutions to see which affected the corals, calerpa, and pods at the lowest dilution. Just an idea.

Synthesized materials are also called artificial, and may be described as straight, where the product predominantly contains the three primary ingredients of nitrogen (N), phosphorus (P), and potassium (K),
might want to direct this towards the reef chemistery thread |
