We received word that Hydor’s new Magnum models 5, 6 7 and 8 will hit US shores in Mid-August. So if you are wanting to upgrade your marine aquarium with some more water flow you could possibly wait to see how well these Magnum water movers will work. We have a burning question wondering if these new pumps are actually controllable and if not is a controllable version coming? Hydor did use this method with the original Koralia models, deciding to release controllable versions later on. We hope these are controllable with common controllers available on the market today, as nobody likes to upgrade twice.
