ok. i did a water change and dripped in my new salt at what i thought was same salinity as my tank at 1.023 (low i know, working on it but that is another story), well i dripped it in over night and my SG actually lowered to 1.020. i have been slowly raising it back up , but now my LR is dying off. Everything else is fine. Is this normal? will it grow back? will i expect to see an amonia spike?
