All sides are like that. It’s hard for me to just accept that it’s OK. I think Redsea doesn’t on the largest tanks? Not following that logic, makes me think it isn’t as strong (the important part) but you can get away with it on smaller tanks to get that clean look for the doors? Eh…
One reason why I started looking at Cade instead of AF for a new tank, but Cade also has an awesome built in solution for electrical that makes it the winner for me, as well as being more proven (i.e. this thread). The sumps on the AF are pretty sweet though. Both systems seemed a notch above the rest, but Cade just seems like they thought a little more of it through.. but they also cost a bit more.
