Pitched weir works great!

We used to use a flat lipped waterfall box, but after time it stopped flowing properly. A stiff wind would cause it to flow backwards. This box by Nelson's has NO issue with wind, flows calmly and perfectly. The pitch to the lip helps significantly. Nice width and depth box for planting or putting additional filter media in. Highly recommend if you're having trouble with flat waterfall outlet boxes.v
