I recently purchased a second hand complete 6x2x2 setup with weir and 4' sump, the return pump is a 130 watt Resun King-5 6000lph.
I've set it up and everything works fine but I have 2 issues with it.
I know many of you like to overfilter your tanks, but the pump is too powerful and moves too much water for my purposes. It's currently returned through a ~1.75" PVC pipe. I know I could manage the current by attaching a spraybar, but it would still be producing, in my opinion, too great a turnover rate.
Which leads to the second problem, which is that it is too noisy. The pump itself hums loudly and I can feel the vibrations through the wooden floor from a couple metres away. I've fiddled with the weir to try and make it a bit quieter by stuffing it with media and inserting a piece of hose in the standpipe to reduce the roaring gurgle, but it is still far too loud. Here's a video of it in operation:

The setup is in my living room and I would like to make it as quiet as the other aquariums in here, which are pretty quiet. Loudest components are in order of loudness: the hum of the twin 4' T8s in the hood of my 4' display tank, the hum of a 3 watt Elite air pump, and the trickling of water from the top-filters on my two 2' tanks.
There is a 1200lph AquaOne canister in the cabinet of my 4' display tank, sitting on a block of foam. I can't hear it in operation unless I open the cabinet doors and stick my head inside.

My ideas on silencing the sump were:
Replace the pump with a 4500lph Laguna, construct a Durso standpipe for the weir, extend the pipe from the weir further below the water level in the sump, add more filter media to the sump to reduce the level the water falls from one baffle into the next chamber.
Anything else I could do?

The question is, with what I've got to work with here, do you think I can silence the setup, or should I get an FX5 and run that instead? And, how quiet is an FX5?

Costs:

Silence sump: Laguna pump, PVC for Durso standpipe and extension into sump and probably a spray bar, extra media for sump, total ~$300, plus labour to acquire components and assemble. Could then sell the sump, media and pump for $200-300.

FX5: $439 delivered, brand new. I know that's an absurd price, I live in Australia. If you know where I can get it cheaper within Australia, let me know.

The most important consideration is which option will be quieter.

Please tell me what you think, and thanks in advance.

With that as your number one goal, get the canister.
You can get most all overflow driven sumps to one degree of quiet, or another.
Trouble is, it usually involves allot of tinkering.
Sometimes, even with a large amount of effort expended, the brute never will get as quiet as a canister runs right out of the box.
 
Cheers Kaiser. Everyone else concur?
 
With my limited canister/sump experience, I agree totally. It took me a few weeks of tinkering with this and that to make my wet/dry filter almost silent with the doors shut. I can still hear the trickling sound of the water hitting the wet/dry from the drain, but it's not all that bad. My Fluval 405 isn't silent, but it's still quieter than the wet/dry.
 
Thanks Watercrawl. Only just noticed I wrote 'of' instead of 'or' in the thread title...
I'm off to order an FX5.
 
FX5s are nearly silent and are great filters. I've seen some quiet sumps after tinkering, but an FX5 would be easier if you don't want to put the effort in and possibly not even get the results you're wanting.
 
BTW look on eBay for them, you can get them new for a little over $200 shipped.

Remember you will have 3 large baskets to fill with media. If you're looking for cheap bio media, look at Pond matrix as an option.
 
$200 FX5 in Australia, I wish. :D
Ordered an FX5 last night and picked up plugs to seal the bulkheads today.
Wondering if I should remove the weir completely when I plug the bulkheads, or leave it and put heaters and the return from the canister inside it. Will end up with some large-ish cichlids in there (female festae, Jack Dempsey, etc.), might be better to keep them away from the equipment and the equipment away from them.

Planning on filling the media baskets with the current contents of my 1200lph canister, plus spare sintered glass media and bio balls I have, will add some more media later if there's space left over.
