Red Sea is actually okay for the Ca
part but the alk
kit should be replaced. When dealing with reef chemistry, low/norm/high is not accurate enough.
I would still start on the water changes in the meantime. You won't make things worse. Just be sure that the new SW
is well aged/aerated for at least a day before use. Once you get more accurate test kits you will know how better to proceed.
Saliefrt test kits should be available at just about any online store. I would see if you can go that route if your LFS
is not able to provide something better.
