In reef aquariums Kalkwasser can just about eliminate phosphate. At a pH above 8.9 phosphate precipitates in the water as insoluble phosphate and flocks out. Marine aquariums kept above a pH of 8.4 allow some phosphate to be bound to rocks and substrate in an insoluble form. Nevertheless it will become soluble if the pH drops below 8.

Is this true, thanks?
Success is to be measured, not so much by the position that one has reached in life...
but by the obstacles which he has overcome...
