I am leaning to wards the sand contributing to the problem more than the rock. My reason for saying this is that when I moved from my old house to the new one I was emptying my skimmer overflow every day, after removing 85% of the sand and adding a bit of rock I am now emptying it every week or so.
I think because of the sand catching the crud under the rocks as we cannot get enuf flow under the rocks because of the sand to remove the crap. this is allowing it to rot instead of being removed by the skimmer which increases the dissolved organics and phosphate in the tank water.
