I have a Saltwater tank that has sat empty (except 1 red legged hermit) for sometime. All #s tested look good:
Ph 8 KH 240
78 degrees Salinity 1019
My concern is Salinity. BC prefer 1023 per 1 post I saw. Accurate? Ok to purchase or H20 changes first?
Our tanks are typically at 1.025, but that is due to the corals. You will find that many stores keep their fish in lower specific gravity (1.020 I think) and fish can do fine. Can you find out the sg of the store you wish to purchase the fish from?
