"The primary material that cause trouble are metals, especially the toxic heavy metals that are often called "trace elements". These toxic materials are often added by aquarists in excessive amounts as additives for no good reason, and in most cases they become poisons in concentrations above those in natural sea water. In addition, most organisms get all the "trace elements" they can use from well-formulated foods."

"In most cases, actually more of these materials probably enter the reef tanks in foods than in additives, and after they get excreted by animals and dissolve in the water they get bound directly into the algae that need them for growth. Fortunately, algae are often exported from reef tanks, keeping the level of trace metals low".
