So I have a tank that has been cycling for about 3 months now. I added fish three weeks in and they seemed to be doing fine(acclimation by floating the bag and slowly adding water to the bag). (5 Damsels, 1 Tang, 1 Clown, 3 Snails, 1 Anemone). The anemone died almost instantly and I added another clown that died after 24 hours. Soon after all of the other fish began to get stressed and die. I thought it was due to the toxins released by the anemone. I made it through a very rough diatom bloom and now have a clean tank. Ammonia, Phosphate, Nitrate, Nitrite levels were all within normal range and stayed that way for the next month or so. I added several turbo snails, 2 hermit crabs, 2 horseshoe crabs, and an Urchin today...they were in the water about 5 hours. Something clicked and I realized that I didn't have a hydrometer (stupid mistake...I know...no judgement please). I went and bought one and the salinity was off the charts. I sort of panicked and continued to remove water five gallons at a time, while adding fresh water until the hydrometer read the salinity was 1.025. Afterward I thought I was a Saltwater Champion.....and then I read several articles that all said not to do what I did. What is the likelihood that my entire livestock that I added will be dead in the morning?
