I have posted several different things about my levels in my tank and trying to figure out what’s going on.. after running into an experienced reefer and talking to them about what’s going on. He told me that he has ran into that problem before, what he had to do was replace the sand and rocks in his display basically redone his entire system. I’m wondering if the possibility of hitchhikers that may have died and they are in my rocks and maybe sand. Should I clean out my tank and recycle it with new sand and rocks? Give me your thoughts
