Review on Tetra Pond Waterfall Filter Replacement Pad, Coarse Pad (19018) - Enhance Your Water Filtration System by Abby Page

This product is supplied without instructions or comments. They don't tell you what size pump to use. They don't tell you where to get a pillow to keep the water from running out of the pond. They don't tell you where to get a charcoal bag or what size to use, nothing. As a result, the waterfall only works for a few hours, then the water flows out of the pond again and the flow rate decreases. Not sure if it needs a more powerful pump or what. You need to communicate.
