The CoralVue booth was full of all sorts of goodies at this year’s MACNA. Besides all of the sweet Maxspect and Elos products (some of which we haven’t even gotten to yet), they are showing off a brand new Sharkman controllable powerhead, which will be Reef Octopus’ flagship powerhead. Like many controllable powerheads on the market, the Sharkman produces a strong stream of water flow at a relavitvely low energy consumption. A two-channel controller allows users to modify the flow rates for a pair of pumps, which includes a pulse mode that can create significant wave action. Only one model was on demo at MACNA, which we believe is an 8,000 LPH (approximately 2100 gph) model, but it won’t be the only one available to this new line of controllable pumps. The Sharkman pumps aren’t wholly dissimilar to other powerheads on the market except in two key areas, their controller and their mounting system. The Sharkman Wave Controller is simple and easy to use, providing a digital readout for the selected speed of the pumps and a countdown timer for the food timer function. Both the speed of the pumps and the frequency of the pulse can be independently adjusted to allow for whatever sort of wave action is desired MORE: Reef Octopus Sharkman Pumps Announced at MACNA
