I disagree, per say, with corals not adding to your bioload. Your bioload is based on one's experience/capabilities, what is learned/utilized, selections of livestock, and the burden one puts on their system. Although fish probably comprise most of a system's bioload, corals do add to it through nutrient import/export, excretions (mucus), growth, competition, reproduction, and not to mention affected by virtually all environmental factors we must atone for.
In reference to the matter at hand, most corals become stressed during the shipping and handling procedures so you can assume they will mucus during acclimation (if you acclimate) and even after being introduced (in-tank acclimation) into the display. The mucus can affect other established corals as well as other new additions so you should choose wisely in how you plan to stock. C. jardinei, Elegance Coral, have been rather sensitive over the past years and usually succumb to infection so it would be wise to attempt this coral once experience has been planted and a well established aquarium has been grown. Multiple corals can be added at a single time successfully, just as long as you understand the needs of said coral(s) and a system's balance is maintained.
