Sorry.. back to the topic of discussion... acrylic dividers is fine.. cut them perfect, glue em heavy, and brace them accordingly.( GPH). If your running a 55g tank with- i would imagine somewhere in the range of 500 to 900gph return.. you would be golden with a 1/4 glass 30 with 1/4 acrylic dividers and minimal bracing on the baffles
