October-November



Over the past two months we have been observing and checking tank 9(A1) daily. Along with daily checks, we have been testing the chemical levels of the tank weekly or bi-weekly. These water tests help to determine the overall environment and how the baby red mangroves will adapt to it. We have also preformed two water changes, due to the extensive amount of red algae in the tank. The red algae population is almost uncontrollable, growing over the patch of green algae in the tank. In addition to the Proposal, we are changing the overall experiment. With more baby red mangroves we have decided to study the environmental behavior of the baby red mangroves by placing them in buckets or pots each containing water with a different salinity. This difference in salinity will decipher the ways in which red mangroves grow in different types of seawater, and how the difference in salinity affects their overall growth and development. Since red mangroves can filter up to 90% of salt water at their roots. This filtration system allows is able to replace sodium ions with magnesium ions, allowing the red mangroves to thrive and grow properly in almost any water ecosystem. From this red mangroves can be grown in various areas of the marine aquarium system including the sump, refugium, mud bed, and in seperate designated aquariums.

From this information we have decided to create a new experiment where we will place the red mangroves in different salinity environments. Over the course of the next few months we will begin the process by taking the red mangroves currently located in the sump and transfer some of them to their new locations. We will start by first placing all of the taken red mangroves in one bucket with the same salinity. Over the weeks will be be taking red mangroves from that bucket and transferring them to buckets with a higher salinity, while leaving one red mangrove stem left in the original bucket so we can collect and compare data. As we separate the red mangroves into environments with different salinity rates, we will observe and collect data and observations to determine at which salinity level red mangroves grow the fastest. Along with growing the fastest we would also want our red mangroves to be healthy and developing properly yet at an exceptional rate. We hope to be able to begin this addition to our proposal and experimentation after we return from winter break.
