Large Scale: If produced industrially: In green houses, large water tanks (raceway ponds), water, fertilizer, pump/ paddle wheel to move it.

The culture medium and tanks need to be protected from contamination by foreign algae, insects and toxicity. Also the level of the pond and amount of nutrients needs to be maintained by regularly replacing the fertilizers and water. Further the temperature and pH need to be maintained. Details on how this is done can be found in the manual. It is useful to replace a small amount of the solution with a completely fresh amount, to prevent deterioration of the culture medium.

Further, tanks usually need to be replaced or repaired after 3-4 years. Other equipment may also have to be replaced.
