Please Help Us. We have had our new 55 up for about 6 months. We purchased an engineer goby from our LFS about 2 months ago. Three weeks ago he died from a bacterial infection we think (he had red lines all over him). The guy at the fish store said to add some Primafix. We did, but he told us the wrong amount. We should have checked, but we didn't . We ended up double dosing our tank. Since then, we have done 2 20% changes and one 10% along with topping off our sump. We always buy our water from the fish store and never had any problems. Since we were worried about our error, we checked our parameters often; except the salinity. I just checked it, and it is VERY high-about 1.038. We have lost most of our corals, lots of snails, 2 anemones and our serpent star. We are unsure if this is from the overdose or the salinity. What is the safest way to combat these problems? How many water changes should be enough to get rid of the overdose?
