The seller designed it himself. I’m trying to figure out how the water would move from each chamber. The left side ( which I would think would be the first chamber) looks like water would flow from below the egg crate filter holder as it goes to the second chamber. Am I thinking if this right or do I have the sides of the sump flipped? Also, please share comments or suggestion on the design as I’ll be getting this system setup soon.
