Product introduction:
The overflow box is attached to the edge of the fish tank and connected to the filter system at the bottom of the fish tank. After starting the overflow box, the water in the aquarium can be pumped to the aquarium through the action of the circulating water pump, and then flowed through the overflow box to the sump, so that the circulation process of the aquarium can be easily realized without turning the hole at the bottom of the aquarium.
