We got up close and friendly with Hydor’s Smart Wave controller and liked what we saw.  This multi-channel control works with existing Koralia Nano, Evolution and Magnum pumps and allows you to put up to 16 Evolution 1400s on just one channel.  You can pick from alternating, sync and feed modes and dial in the interval level to match your needs.  While this system has been available in the US for several months, many hobbyists are still unaware of its’ existence, so go on over to their site or even Marine Depot and check out the full specs.
