The Koralia Nano Evolutions are available in two different flow rates, 240 and 425 GPH. Thye are designed specifically with wavemakers in mind and are a fraction of the cost of a MP-10. You could get two nano Evolutions ($24 ea.)and a Reefkeper Lite controller ($95) standard with 4 controllable outlets and a temperature probe for about what one MP-10 sells for and have more functionality. Quieter too.
