I have a Gyre pump but it's the Glamorca brand. Most of the time I want to throw it against the wall. I haven't owned the maxspect version but they are very similar. Mine gets noisy most of the time it's running. It's been doing that since about a month after setting it up. My only advice is try to carefully play with the end pieces and see if you can get them fixated in a silent position. Remove the pump from the water and adjust the end caps by twisting and pulling slightly while the pump is running maybe at 30 or 50%. If you can make it silent this way, then don't touch the side end caps or plastic sleeves (whatever they're called), turn the motor off, and place if gently back into the water and turn the unit on and see if it stays 'silent'. I just did that with mine tonight. One side wasn't even working.
These units in my opinion are super tempermental and probably need adjustment periodically when you clean them at least.
Also I noticed when I put it on reverse mode for a minute it seems to go back to being quiet, but that only lasts a little while.

I own the 230 and the 250's. I originally installed the 230's on my 75 gallon tank but upgraded to the 250's because it sounded like a cell phone vibrating when it was running at full speed. With the 250's I can run them at 70% where there is no noise level and it moves more water then the 230's at full power.

The great thing about having the pair of gyro's on the new timer is the diversity in the programs you can run. I cannot run mine in reverse mode because it stirs up the sand bed.

I prefer not to set the program and walk away. I like to change it every day and night. It takes only a couple seconds to change it.

Play with it and find out what works best for you. I prefer the more random modes as it changes the way the water moves in the tank.

Be careful if you get the timing just right (or wrong depending on what you want to do) you can create a wave that will spill water out of the top of the tank. For my tank it is alternating every .7 of a second. If I run these babies at 100% it will get the water rocking and spill water out of the ends of the tank.

It can also stir up the sand, gravel big time and knock corals over if improperly aimed.
