Would it be better to use live rock in the back on an AIO tank instead of bio filters like seachem bio matrix ??

I agree 100% here. I don't understand what those matrix type products and bricks do that a rock won't do. And, I think some people believe that some of the blocks they've tried leached metals into the tank. I'd go with the live rock personally.
