I am just speaking from my experience. I was able to neglect the tank when it had a lot of foliage in it just like Cliff. One day I had the bright idea to thin it out so I could see the shrimp better. I think that the upset in the balance in the tank. So disturbance in the tank + plus lack of plants to process the excess nitrates + neglect = fatal combination :( -- -Bryan _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
