My trumpets are slowly receding and the Duncans have not opened for months. I'm not sure the smaller water changes are sufficient to eliminate the toxins from the coral warfare. The filtration, carbon or otherwise, may not break it down or remove it. I am contemplating doing periodic large water changes as a test. So, far the larger changes have had a positive effect on the tank inhabitants. It is obvious to me that the water quality in my tank needs to improve. Please keep us posted on your progress. I watched the Prefect Storm movie last week, kinda depressing, but I do see some strong similarities in reefing!
Thanks,
Gary
