text: Note that an aqueous solution of water with chloride ions, when electrolyzed, will result in either OH− if the concentration of Cl− is low, or in chlorine gas being preferentially discharged if the concentration of Cl− is greater than 25% by mass in the solution.
text: It is safe to say, however, that far less is known about such issues in reef aquaria, where unnatural materials are often added (e.g., chelated metals, iodine as I 2 , etc.) and concentrations of certain species may be far higher (or possibly lower) than in natural seawater (metals, organics, phosphate, nitrate, etc.).
text: However, as the ideal saline concentration of a salt-chlorinated pool is very low (<3,500ppm, the threshold for human perception of salt by taste; seawater is about ten times this concentration), damage usually occurs due to improperly-maintained pool chemistry or improper maintenance of the electrolytic cell.
text: In spite of its great biodiversity, concentrations of chlorophyll and nutrients in the Mediterranean Sea are very low, making it one of the most oligotrophic ocean regions in the world.
text: But the concentrations are so low — averaging between 50 to 60 parts per billion (ppb)
