I want an easier access point to get into the tank when needed, thus the reason for converting the front into sliding doors. I know it'll cost more, but I'm short and the stand this things going to be on is tall, so getting into the tank itself is going to be a nightmare from the top vs a front sliding doorway. We're thinking of using 2 acrylic sheets instead of glass so that they don't weigh down the railings for easier sliding. Yes, I'm leaning more towards tossing the divider idea altogether. Also, we want a water feature because I want some community fish in the lower half and I love waterfalls, so that's something I won't budge on.
