Thanks all,
Yeah Kurt, I need to update you. I did finally get that copper test kit in and somehow we did have copper in our tank. Not sure if the trough was the culpret or not. ( I think it was a rock from Petco, they treat ich with copper) That is why only the snails and shrimp were dying. We used all of the things you all suggested and it got all of the copper out (polly filter). copper tests 0 now and everything is doing great. I did just add in the last couple of days a new Scott's fairy wrasser, cooks island. I will try to get some pics soon. He is beautiful. Since my scallop and coco worm have been doing so well for almost a month now I am thinking about a clam next, maybe in a month or two. Any suggestions on what kind?
