Overflow Box

An Overflow Box is usually integral to a Sump Filter. The Overflow Box is placed in the tank and if the water released by Wet & Dry Filters into the aquarium, is beyond the manageable level, the balance water flows to the Overflow Box. This water in the Overflow Box is then reverted to the Sump. Therefore, an Overflow Box helps keep the aquarium water level consistent. Fresh Marine offers some very effective Overflow Boxes by CPR Aquatic. The ensuing discussion delves with some of these Overflow Boxes.
