Are you satisfied with the Kent Marin? I'm using Reef Crystals and am wondering if that's the problem? I've never had Alk issues until setting up this tank. This is a new batch of salt mix too.
I've only started using the Kent salt about 2 months ago. So far it's been good. Haven't really tested much lately. ( I'm not a test person lol)
