If you switch from Instant Ocean Reef Crystals to kent sea salt or seachem, you will kill everything in the tank, at least in my experience. Certain salts don't mix well with each other.
We have been using reef crystals. We have had to dose for calcium/alkalinity. It could be from our clam, but maybe not. Is reef crystals natural or synthetic? Can we switch to oceanic with no problems? Is there a list of what salts are natural and which are synthetic?
