Designing a sump for my 180 Gallon tank

  • We are currently upgrading MFK. thanks! -neo
Yeah looks like it to me too.
Ive used the thick Weldon to fix stuff like this. Dont remember the number though sorry.
If it is just around the overflow box I dont believe you need thick Weldon because the pressure inside and outside the overflow box are the same if your standpipe is high enough. It is more so to seal the box and hold it in place
