Collect two liters of seawater from an independent feeding tank and pour it into an Artemia hatching container. Next, connect an air pump to the tubing connected to the bottom of the hatching container, and let it run for approximately 10 minutes before adding the Artemia cysts. While waiting, measure eight grams of Artemia cysts using a weighing balance.
After 10 minutes, pour the measured Artemia cysts into the hatching container. Next, prepare the feeding tank by placing the feeding container into it, ensuring the top remains above the water surface. Connect the outer portion of the feeding container's corner tubing to an air pump that supplies air to the bubble stones to ensure proper water circulation during feeding.
To enrich Artemia Nauplii, add 1.5 milliliters of enrichment diet to the hatching container two hours before the desired feeding time. After two hours, turn off the valve supplying air to the hatching container. After placing a light source at the base of the hatching container, cover it with a cardboard box to exclude ambient light.
Allow the light to attract Artemia Nauplii to the bottom of the container for five minutes to separate live Artemia Nauplii from empty shells. After five minutes, remove the box and light source. Place a three liter measuring jug beneath the hatching container.
Detach the tubing from the hatching container, allowing the Artemia Nauplii and seawater solution to flow into the jug and collect one liter of the solution within close proximity to the feeding tank. Pour the Artemia Nauplii and seawater solution through a 100 micrometer strainer to separate them from the sea water. Then rinse the Artemia Nauplii inside the strainer twice with water from the feeding tank.
Place the strainer into the feeding tank to unload the Artemia Nauplii. Next, stir the water in the tank to evenly distribute the Nauplii throughout the tank. Move each hanging bar with the attached coral colonies from the culture tank to the feeding tank.
Ensure the hanging bar is securely positioned across the top of the feeding tank. Remove the coral colonies after the four hour feeding session by taking the hanging bars out of the feeding tank. Thoroughly rinse each coral with sea water from the respective culture tanks.
To remove residual Artemia Nauplii, place the hanging bars with the attached corals back into their respective culture tanks.
