You have to be very carefull during the interpretation of many of these papers for the simple reason that a lot of the reserch, particularly concerning inorganic phosphate chemistry is - and has to be - done in abioitc systems. In natural systems, with a normal bacterial and microalgal flora, phosphate is limiting and it will never be accumulating in the sediments. It will be taken up by the organisms in the sediments before it gets a chance to react otherwise, in other words the phosphate is not the sediments proper, but rather in the bacteria and microalgae covering them.

(the above paper is interesting - but again, the data are from abiotic systems at levels far higher than are found in reef tanks. Be sure you calculate the values for adsorption using reef tank values using their forumations...)
