Upgrade time !

I had a similar noise when I was setting up my tank. I am using a herbie, and although I could dial it in so I was getting no suction noise, the noise of the water splashing over the overflow was louder than I wanted. I just went 1 step down on the return pump (speedwave). Works well so far, but my next task to to get my reactors online, which are T-ed off the return pump. This will mean I have to step the pump up again, which will mean more adjusting.

Ok thanks ill try that, Yea my reactors are already plumbed in so I'm good there, this tuning is going to be the end of me

[Craigdillman]

Yea that worked pretty good I went one setting down on the pump and it's is almost dead silent

Because of a lack of drop between my tank and sump, I don't use my drain valve to dial in anything. Instead, I have to dial back my pump with an 'exhaust' tee back to the sump. But it's the same principal

My overflow is very quiet
I currently have my main drain standing at around 5" below my overflow teeth, my emerg drain between 1/2" and 1" from flooding (haven't measured it), and I run my overflow box level within an inch of the emerg height. It fluctuates some, but never gets my emerg plumbing wet. And I like it that way as I have horizontal runs to my sump so don't want any stagnant water. Nor do I want a constant slow trickle. I've done it this way for nearly 18 months and am happy with it
I don't even have to adjust the valve anymore

For you, once you find the heights you like for your pipes and water level, I'd suggest you dial in your system to run your pump full out
Then just live with the overflow teeth noises when you dial it down

PS

I found when my system was brand new with no slime on anything, the overflow was noisy due to surface tension
I ran my finger across the top lip of the box and most of the noise went away

I haven't even thought about it since as it's super quiet

Ok so update time got the overflow dialled in pretty good ended up having to turn my return pump down a bunch but its probably for the best cause now my sump isn't rocking
Tests
0amm 0 nitrites 0 nitrates, soooo put 2 chromis as test fish and they are doing great so far eating and schooling (ill add my other 3 from the other tank soon)

And video of my clowns hosting my acan tonight

Glad to see you solved the noise issue
I somehow missed your's and Ian's posts before my last

[Craigdillman]

So for flow in this new tank I got
2 vortech mp10s on each end wave mode, seems to be doing ok but may need more flow in some spots wife approved of another/more powerbeads so before she changes her mind...

Im thinking of adding either

1-2 wp25's one on each end putting each mp10s on back wall

1wp40 and ramp it down

what u guys think?

Regarding the photo of your shelf bracket light hangers. First, I think that's a great idea. Second, the brackets do not appear to be perfectly centered on your tank. It looks like they are shifted to the left. This is either a trick caused by the angle the picture was taken from, or they really are slightly off centre. I understand that if they are off it has no practical consequence as you will hang your lights from a bar which is supported by the brackets. It's just my OCD that cringes! If it doesn't bother you, Im happy for you! It means that you are free from feeling anxious if meaningless things don't line up as they are "supposed to".
