I just wanted to update this thread and make a few suggestions. Make sure you use thicker acrylic then I did for the sump baffles. Mine were too thin and didn't hold well. I ended up running beads of silicone along the edges of all of the baffles to keep them in place. Once it was filled with water and had actual water pressure against it, it was pretty flimsey.
I didn't want to take any chances of the baffles letting loose once it was under the stand. I would not be able to repair it under there and I already have to tear the tank down or cut the center brace to get it installed.
So my moveable baffles are no longer moveable But it's sturdy now. Now I just have to get it installed. I'm tired of looking at on the floor next to the tank.....ya just know I'm gonna cut the stand's center brace don't ya??? Please don't break.....please don't break.....please don't break...................
