hi guys i am doing a water change an i just runout of Reef crystals before reaching the 1.025 mark. can i add a different salt (other that reef crystals) to make that salinity requirement? or would i have trouble reading water parameters? btw, i do not have much in tank. couple anenomes pulsing xenias and loads of green mushrooms. i intend to add some more softies soon. thanks for your response.
