This was going to be my suggestion . I have been using it for 2 years now and haven’t had an issue. I know some people are chasing the latest and greatest...trace elements included etc. I guess it depends on your goals and system demands. I’m a keep it simple person, use what works and have a bunch of fish for nutrients lol.
