Just an update....finished the sump, it's not pretty, nor bubble free, but it holds water
.... I cheaped out and just braced the ends.... When water testing, I filled it completely up and there was no detectable bow, by eye anyway. Considering what I have to pay for acrylic here, decided this would be good enough.
Marc, FYI, the refugium overflow seems to work fine. There are a few large bubbles, but nothing a couple of pieces of rock can't fix and it's quiet, which was my goal, couple more things left to do to it, but so far so good....
Thanks for the help.....Can't wait to start the next project....
