I do like it better even with the noise. Having the try side of the MP40 stick out so much is starting to make me nervous, my oldest is nearly to the point of being able to reach it. I am sure at some point she'll get curious and unintentionally pull it off the tank! haha Of course I do still have the gyre magnet on the outside of the tank, it is smaller and I have it up higher on the tank. The wide flow that the Gyre produces is a lot better for my tank and the rock structures I created.
From the few threads I've read and the responses I've received the Gyre noise will reduce once the pump breaks in. I had the pump set to ramp from 10-50% quickly and that was loud, the setting I have it on now gradually increases which reduced the noise.
Time will tell, the defining moment for me will be cleaning the gyre. Cleaning the MP40 is SUPER simple since the wet side doesn't have any cables. I've seen some people just soak the gyre in vinegar without taking it apart, I figure once I get the other gyre pump I can alternate cleaning.
I shot a video comparing the two pumps, the only factor to keep into consideration is that the Gyre 230 and MP40 don't really compare when it comes to water movement. The MP40 is a bigger pump and it capable of moving a lot more water. I primarily focused on noise, once edited I hope to have that video out in a few weeks.
Yeah i can see my son pulling on that mp40 too. He's getting bigger everyday. I had first Gen Gyre and it was loud. It did die down but was still loud. Cleaning the gyre was a pain i hated it. Also i do not like cable in water. Well whatever it is let us know how it worked out
