Fusion 20 Return Pump

[skrillay0]

I just set up my Fusion 20 with the stock pump and its super loud. I tired to hang it without the cups and made sure it isnt touching anything still no luck. What are your suggestions on a super quiet pump that will work/fit in the rear chamber. Im running a Rw4 in the display for more flow also. Im willing to sacrifice GPH for Quietness.

 

Thanks

I had the same issue and found that the pump was not stuck in place with the suction cup mount. I reattached the mount and it's much quieter . I can still hear a light hum but it's much better. I also have the rw4. What a great little wave maker . I m running it on low because it really gets cranking and becomes too much motion.

any luck with a replacement pump? or other solution?

I replaced both the return pumps in my JBJ 28g with Cobalt 900's, super silent now. I would say any Cobalt pump that has as good or better flow than stock and will fit in your return area would be a decent choice. Warning, do not get the MarineLand versions of these pumps, much cheaper and I found out why.

I ended up using the Cobalt MJ900 myself which was way better than stock and way quieter. I have parted ways with this tank and started a Fusion 10 again.

 

Now my stock fusion 10 pump is quiet but blows micro bubbles into the Display.

Waterfall into your return chamber creating bubbles that your pump sucks up, most likely.

the water level on the return chamber is only 1/2" from the second

 

I even filled it so it sits even to test it out.

Doesn't take much, if you can see bubbles at the top where it flows into the return chamber there's a good chance the suction of the pump is pulling some of those bubbles down to the pump intake. The pump itself cannot make micro-bubbles unless it is getting fed air from somewhere.

Are there bubbles spilling over into the return chamber, maybe being created somewhere else in the AIO. Unless there is a large air pocket trapped down near the pump I can't think of any other way it would be making microbubbles. Can't make the bubbles with out some sort of air input.

Jebao makes a DC2000. The pump is dead quiet, its tiny, and has variable speeds. $47 from China. ( Fishstreet ) I think shipping was less the $10. I dont know why this pump is not readily available here. Best small pump I have ever bought! They also have a DC1200. Both would be overkill for your new 10 but they would have worked in you 20.

I finally figured out the micro bubbles. I got IM to send me a new nozzle and return hose and replaced it.

No more micro bubbles
