So, I added 2 peppermint shrimp, and a watchman goby to my tank yesterday. Fusion 15 AIO (only the two shrimp for a few days until I could get with a friend to pass his off to him). Did a 3 minute freshwater dip, temperature acclimated to my tank for 20-30 minutes before doing dip. Dip went off without a hitch. Original salinity from shipping container was indeed low, but seeing as how 0-35 was more drastic.... Temp acclimated the shrimp for the same amount of time. All the inhabitants were in good shape as of last night, acting normal and even eating. When I got up for work, one of the shrimp was dead (12 hours later, and the one that had eggs), and the other shrimp had molted (definitely a molt, I used to keep freshwater shrimp). Removed the body. Came home, and the other shrimp, and the goby were both dead (22 hours later). Nothing apparently wrong with the bodies (CUC had started doing their job..) I have a clown fish, and 2 zoa frags also in the tank. Clown seems perfectly fine, and I can't see any kind of issues on the fish. I tested the water after the deaths, and it is as follows.
NH3/NH4 - 0.2 ppm
NO2 - 1 ppm (Red Sea and API)
NO3 - 10 ppm
pH - 8.0 (API and digital - I can't see well enough for the Red Sea pH)
Alkalinity - 9 dkH
All the parameters were stable (slight uptick in the ammonia, but I figure my issue explains that). I don't know why these inhabitants died. I'm new to saltwater, so I'm looking for answers as to what I could have potentially done wrong. The only thing that I have changed recently was removing GFO from my filter, and adding PolyFilter on 2/18.
I may have posted in the wrong sub forum, I'm really not sure, but apologies if so.
