Have you been adding something to raise your alkalinity? If not, I would question the reading/test kit. What kind of water are you using to make up your saltwater? Unless your new saltwater is equally high in alkalinity, water changes should help bring it down. By the way, welcome to Reef Central; it looks like this is your first post.
