DD Ultraflow Overflow Weir Comb 60cm Reviews

D-D Ultraflow Overlfow Weir Comb 60cm The D-D Ultraflow Overflow Weir Comb is designed with a unique vertical and horizontal drain slots that allows around 30% to 50% more water to flow through the slotted sections compared to a vertical type weir, which in normal circumstances, can result in a much higher running level.   The problems normally associated with older style overflow combs result in this higher tank running level, touching the glass bracing bars or often overflowing the aquarium!  The Ultraflow Overflow Weir Comb maintains a high flow at all times, resulting in a higher flow -through, allowing the hobbyist to use larger return pumps with a higher flow rate.
