Hi...LOVE your pooch!
How tight is that lid? What did you find out about filtering the tank without leaving any escape routes? The octopus is my all time favorite critter, a creature I will never own, but love nonetheless. I'm so looking forward to your build, and see how you do this.
Thanks flower. I'm going to duct tape the glass top down. And the area of the tank where the plumbing goes in will be stuffed with foam. I think that will seal up the tank pretty well.
And rosey says hi...
