To begin, perform leakage inspection for system safety by inspecting the baseboard, seam, and connectors for water stains or droplets. The transparent nature of the system's cover shell facilitates visual inspection of water leakage. Extract 10 milliliters of seawater using a syringe from the three-way valve between the activated charcoal and seawater module.
Dissolve the additives in the extracted seawater and inject the solution back into the system through the three-way valve to replenish the system with nutrients and other reagents. To reduce toxic concentration and eutrophication in the culture system, exchange water by switching off the power of the entire system and unplugging the power cable for safety. Then remove the coral culture module and connect the outside wastewater pipeline to the outlet in the seawater store module.
Now rotate the system and position it front side down. Turn on the outlet and allow the seawater to flow out from inside the system. Discharge the required amount of seawater and take off the outlet.
Afterwards, reset the system, and inject the newly-prepared seawater through the water inlet. Reinstall the coral culture module into the system. Switch on the system and wait for the system to get back to normal.
