I switched from Red sea pro to HW Reefer salt and Love it. Its a fully synthetic . I have sps frags that all I do is a 5 gal water change weekly and am getting nice growth. The only problem with this salt is the only place I have found that sells it is BRS. When I did the change I did 5 gal water changes and just introduced the new salt in my weekly water change cycle. btw this is for my 30 gal tank.
