I just had another small flood. :frustrat: I thought I finally had it all figured out last time I remodeled the tank but shortly after I got it up and running last time, I started to have my doubts. I could visualize a better way but that meant taking it all apart, and drilling the sump again. After my mini flood yesterday, I finally had the motivation to do just that. I just got done with my FINAL remodel. I moved the overflow from the sump to the fuge down to the bottom so it has a constant syphon. It works much better now and if it ever floods again it's cause I did something stupid!
