seriously though there might be a little buffering going on but not enuf to stop a tank from crashing if not helped. there were sand comparasons done a while ago whare they set up tanks with the 3 different types of sand.. they all had PH crashes with in a time period and the results were that a sand bed will not buffer a tank enuf on its own.
if you think about it the place the desolving is happening it would be at the bottom of the sand bed, maybe a little makes it throught the sand to get into the water coulme but I would guess most of it is just turning to finer substances and remaining as your bottom layer of the sand bed. because they are breaking down into smaller particles they take up less space and compact a bit.. therefor your sand bed settles and "Appears" to be desolving.
