Could you please be more specific ?
I didn't design it, it is a pre built set up from AquaOne.
What is wrong with the desing ?
Cheers
Hi Luisedumuller!
Just to let you know I am having exactly the same problem!! The only thing is that mine is the Aqua One Mini Reef 150l. instead of the 30g. (i guess yours is 120l.)
I have tried with and without the 'decibel level' is the same (I downloaded an app to test it...)
I have tried to find a solution but nothing convincing so far. Have you been able to solve it?
By the way for those who might be able to help:
1. It is a complete aquarium, it comes with its return pump (cannot be tuned) and with its plumbing (supposed to be adjusted).
2. I have tried to reduce the speed of the water by blocking partially the end of the downpipe (from the DT to the Sump). Even though I knew it was not a good idea to avoid eventual overflows...I just wanted to try it -> no success
3. I have found this forum with members with similar problems: http://www.masa.asn.au/phpBB3/viewtopic.php?f=148&t=263512
I realise now that this post is from Aug 2015. Have you been able to fix it Luisedumuller?
Cheers

I don't even understand how the baffles are doing anything.... the water level should be at the height of the baffle closest to the return pump ,that dictates your skimmer height....am I wrong?
I have the minireef 120 and also had a big problem with noise in the sump.
To quieten things I was supplied with an extension for the drain (supplied by aquaone customer services in the uk ).
If you wanted you could make your own using a 40mm push fit connector and a small piece of 40mm pvc pipe from any hardware store and I also replaced the return pump for a 1200 lph unit with an adjustable output which I run at about 65%.
If you do not want to spend on a new pump you can always just buy a 20mm ball valve and fit it to the return hose as it will do the same job.
All I can hear now is a very slight trickle from the corner weir if get close up to the tank.
The next problem re noise that you may encounter would be the skimmer but most people replace the aquaone unit as a matter of course as it is said to need constant monitoring and adjustment ( atm I have opted to run the tank lightly stocked and skimmmerless changing 3 litres of water a day plus ro top ups and a 10% water change per week)

If you are down to a 1200lph pump at 65% with some head loss you are probably running at say 600lph. Is that enough flow through the sump? I have the 90 and this is my concern with lowering the flow to eliminate the noise. I've already extending my drain BTW and that did make a big difference.
yes, that is a concern of mine but I have added a rw4 powerhead for circulation and the pump can always be turned up if it becomes a problem when I add more stock.
Aquaone originally supplied a 2300 lph pump with the 120 l tank but down graded to 1300 lph last year because of noise issues.
Most people seem to be using a valve with their minireef systems either on the return or the drain.
atm i have just a piar of small common clowns and a pair of cleaner shrimp.
Fish wise I am only going to add one more although a bigger cuc will be needed.

Maybe put a V at the end of the pipe. I would def. try a adjustable pump or add a valve. I know with the Red Sea Max, I had noise but they added a adjustable flow valve on back by the overflow. Took a bit to find the right setting, but almost silent now

I plumbed in a Vectra M1 today to replace the 2300 that came with mine, having calibrated it I can run it anywhere from a trickle to niagra falls and set it to ramp up/down when I like. A bit of an extreme solution given the change of plumbing has cost a fortune, but the wife should be happy now (unless she finds the receipt).
Thhey mention that the pic with the water over all the baffles was with their return pump shut down
