Humming and excessive noise are typically due to propeller being unbalanced. This is one of the drawbacks I see in the Sureflow kit design in that for some reasons they opted to make the shaft and propeller all in one unit. IMO it would have been better to use a real RC boat propeller where the propeller is much more precisely engineered and manufactured. Their propeller blade is a bit too thick and may offer much more resistance and drag than a typical RC boat prop. This will cause more vibration and noise IME.
Why reinvent the "wheel" (re: propeller) when you don't have to is my thought.
Anyway you can see about balancing the prop and see if this will help. Basically run the mod outside of water without the shroud on while using your hand to to keep the shaft centered. run the propeller against some fine grit sand paper (careful that you don't take away to much) until it is quietest and smoothest. The caveat to this is that as you shave away the prop, the flow will lessen a bit but IMO nothing all that drastic.

I called eco mod and you can only get it from a dealer and it is about a moth or so out. Hope that helps

the Eco mod doesn't come with the cool mount though.

Was just about to say that!!
I would be very interested to see the build quality.

A gyre flow is a circular flow. I plan to alternate my flow between clockwise and counter-clockwise directions:
dhnguyen,
I'm with you regarding controllers. I can't find a pump controller that can switch the flow every 15 minutes. The longest switching period is 7.5 minutes on the Reef Fanatic. The fast switching will void the warranties on many pumps (i.e., Tunze 6025).
I will probably place my pumps on the X10 system that operates my lighting circuits (12-hour daytime actinic & 12-hour reverse daylight photoperiod). That means my pumps will alternate the gyre flow every 12 hours.
I hope my sand doesn't pile up too badly over a 12-hour period. I'll probably use a smaller pump (MJ-600) for a gentler flow.

cool that you are getting one!
obviously there will be a difference in fwd pressure, but dont these mods disperse alot of flow out to the sides as well?
also just curious, how many of you guys go out of your way to get a few GPH's behind your LR? i found that there is no difference in water quality, and if you have enough flow on top of the rocks, it will find it's way back through them.

This is how you test the flow rate. It will be easier to do this with 2 people.
Connect a large inflatable plastic bag (at least 2 gallons or so) at the output of the pump. Turn on the pump submerged and time it for a predetermined number of seconds. Then measure just how much water is displaced into the bag. The rest is basic math to figure out the GPH.
This is exactly how many pump manufacturers test theirs too
