Precision Marine is showing off their new overflow boxes here at Reef-A-Palooza in single and dual flavors. The new overflows are rated for 400 GPH on the single and 800 GPH on the dual and are made from smoky acrylic. One nice feature is the overflow is notched but unlike the traditionally notched overflow, Precision Marine uses offset notching where the notch is about 1/4 in. below the rim similar to what you find on built in overflows.
Both overflows offer a check valve to keep the Weir overflow free bubbles using a small water pump. The single tube Precision Marine OF1 measures in around 6.4 x 7.75 x 7.7 in. and the dual Precision Marine OF2 measures in around 10 x 7.75 x 7.65 in. Although the overflows use the perforated standpipes and sponges to quiet the flow, it would be nice to see a dedicated, quieting standpipe incorporated but nothing a little DIY can’t solve. The Precision Marine OF1 single overflow with retail around $85 and the OF2 dual for around $125.
