A Collector Box is included in the two largest pond systems.
The Collector Box serves as a junction box and a pre-filter. It allows for up to four - 4 inch drain or skimmer pipes to be connected to the pond side while the opposite end has two - 3 inch outlets for connecting multiple pumps. Each of the 4 inch return line openings has a slide valve built in, to adjust water flow. The box comes with a large removable net for filtering out debris.
The Advantage Collector Box is available in two sizes:
Small comes with 3 four inch inlets - Dimensions L-33" W-28" H-25"
Large comes with 4 four inch inlets - Dimensions L-38" W-32" H-27"

You should stop feeding your aquatic plants about a month before the first frost in your area. Even in areas that don't normally have frost, plant growth slows in the shorter, cooler days of the fall and winter months.
