Since my brother co-owns our tank, I have ran into more problems because my brother heard some stupid advice from some idiot at Petco. One thing he heard was to keep SG at 1.021(he now knows its wrong) so we have had trouble with coral because of it but now it is back at 1.026. P.S. I do all the work and he just sits back and looks pretty, he doesn't even feed the fish when I am somewhere else for a night! The only thing is that he does help pay for stuff which is a plus.
