Hey all, i used to have a tropical setup, now i have moved to marine

had a damsel in the tank but died after 4-5 days

now i left the tank for a month just cycling and today got water tests done, water is fine.

now i put 2 damsels in there today but they look like they are going to die,


shop salt level was 0.21 - 0.22 mine is 0.22 - 0.23

also can you use kettle water to put more water in

sorry bout being thick

thanks all
