All typed of macroalgae (shaving brush, etc.) die within a few weeks (except cheato). Shaving brushes often die, poor survival in tanks
the fish die in different way. mandarin died within 2 days. pearly jawfish died within a month. clown goby died within a month. I don't remember the other fish right now but its the same time frame. sexy shrimp died one by one over the course of two-three months. peppermint died one by one over the course of 4 months. Almost every one of these fish/shrimp have high tank mortality rates
I will check the stray voltage today with my meter. I will also double check the temp with some other thermometers.
As for the water quality, yes its the same source water but the interaction within the tank is what I think is different. You guys think not enough live rock? Maybe the sand-bed is screwy? Its only two inches and it was brand new when I put it in the tank so I don't see how.
Do a 100% water change just to be sure, but I suspect the fish and shrimp choices and perhaps where they might have come from. After the change, put some tough fish such as damsels or clowns in and see how they do. Later can swap out for more challenging species.
