that gigas is nutz!! I bet is just sucks the nitrtes and ammonia right out of the water. thats hot. When mike palleta was in town a few months ago he mentioned that his buddies, who farm clams, pee in their clam system. That was their "secret recipe". Ive always wanted to get a bunch of small deresas or even oysters in a sump just to cleam the system. Besides the calcium. I bet they would keep SPS super happy
