I've been keeping reef tanks for a long time, and using Koralia powerheads pretty much since they were first introduced years ago. In my 75g mixed reef, for example, I had 2 Koralias running on the wavemaker function on a Reefkeeper 2 controller. They actually did a decent job of creating a good amount of alternating flow. They are often a little noisy when they start up every cycle, since they use a mechanical stop to induce the propeller to turn in the correct direction. Since the two in that 75g tank had been running for almost 2 years (I don't think I had even cleaned them in the last year), I was sure they were about due for replacement, and I started looking at the Maxspect Gyre 200 series models and the Advanced Controller as a different option. A new pair of Koralias would be about 1/3 the cost of the Gyre and controller, but I really liked the idea of the Gyre.
After 2 weeks of research, online reviews, reading countless forum threads, and the obligate hand-wringing, I decided it was the right move. I just needed to decide which model to buy. My choice was either a pair of the FX230/130 or a single FX250. The cost difference wasn't huge between these options. I REALLY did not want to end up with too little flow. Since the pumps and controllers are not interchangeable, if you change pump models, the controller and power supply also need to be changed. Since the controllers allow you to adjust the Gyre speed from 100% to 10% for any mode of operation, I could always dial back the higher flow FX250 as needed, and ultimately, I chose to go with the FX250. With the FX250, I had no doubt that I would never need the higher flow settings in this tank, and I would always have surplus flow in reserve.
Much consternation followed about setting up this system. The Advanced Controller, even after watching the CoralVue videos several times, was pretty intimidating. It has tremendous capabilities and myriad options for a controller with only two buttons and a dial, and I really dislike multi-function buttons. I don't like having to refer to the instruction manual every time I want to make a simple adjustment, but I probably have resigned myself to frequently doing just that with this system. As it turns out, most of my worries were unfounded, and working with the controller is much easier than the rather weird Maxpect manual had led me to expect.
