So I just noticed a small crack in one of my sumps. Not leaking though. Sump is a 30 gal, DT is 125. I have a 55 gal tank I am not using, so i am thinking about making it a larger sump to replace the 30. Any suggestions? Also I was going to drill through for an external return pump. Any suggestions on what pump? I think it will help with less heat and run quieter.
