Maintaining high flow through a standard a weir comb isn’t an easy task, weir boxes are usually manufactured to be as small and unobtrusive as possible but that often results in the display aquarium run height backing up due to the short linear length of the top of the weir glass and to the added restriction of a standard weir comb. The D-D UltraFlow weir employs horizontal and vertical drain slots allowing around 30-50% more water to flow through the slotted sections compared to a standard vertical overflow comb greatly reducing the water run height of the display aquarium. When employing restrictive standard vertical weir combs water can start to back up in front of the combs and to touch the brace bars or at worst overflow the aquarium!!.The higher flow through the weir comb also allows for higher output return pumps to be employed . Designed to retro fit existing aquaria or for installation as part of your new aquarium build. Adjustable glass runner for 6,8 and 10mm glass. Can be installed on glass over 10mm thick by cutting the runner and bonding it directly to the glassEasily removable slotted section for easy cleaning and to maintain high flow Available in 60cm length
