Bought a bottle today and decided to dip a few corals out of the frag tank, as I followed the instructions to a tee. As I put them back in frag tank after double dip rinsing all my shrimp went upside down and are now in a a dif tank about dead. Im hoping that they come back its almost like they got knocked out!!That's a 4 pepermints, 2 cleaner , and 1 scarlet. My mandren, scooter,wrase ,Pom Pom crab,crabs, snails seam to be fine . So I don't know if some chemical affects shrimp but it was almost instantly.
