After setting the micro drive system, add one milliliter of the commercial microbiome source solution into 500 milliliters of the seawater while stirring. Next, inject 50 milliliters of the diluted solution and 10 microliters of the commercial coral nutrition solution into the circulation system. Switch on the inner circulation pump and turn on the air pump to culture the microbiome for 21 days.
Cut the rock coral branches into a length of three to five centimeters. Adhere these coral branches onto 3D-printed coral support bases. Place the coral branch samples back into the original seawater tank for a minimum of seven days for recovery.
Fix the coral support base onto the rotation unit using glue. Assemble the coral culture module and connect it to the outer circulation loop. Position the camera on the top of the studio and capture the images from a vertical view.
Next, place the coral culture module in the mini photo studio with the coral positioned in the center and at the bottom. Capture coral images by rotating the outside handle. The coral culture module effectively controlled the seawater temperature and prevented temperature fluctuation, which can strongly affect coral survival.
The sample corals'tentacles extended over one month indicating that the system provided a suitable survival environment for the coral.
