Talking to a guy today at a store and told him about my setup and how I no longer use them for my tank and he told me that it's best not to run socks for a sps tank. Not that it causes harm to the corals but the particles that are floating around the setup actually feeds the corals and sps grow faster without socks because of this. He explained to me that socks actual take away food from corals. Anyone agree or is this another theory to be taken with a grain of salt?
