Upgrade time !

[Craigdillman]

Lights are going to be tricky when the tank swap happens cause I can only run one tank at a time and when I put the lights on the new tank the only tank will be without lights and don't have another light (other than a par38 for the fuge) but ill cross that bridge when I come to it

Well water sand and rocks are in! The right side is mostly bear cause I have about 50 pounds coming from the other tank going there that will be a zoo garden and I'm going to make the structure connect to the 3rd island (ill take some close up shots of the rock work tomorrow )

Looking good

Hey guys,

I need some hell in tuning the herbie overflow I can't seem to get it silent and I'm not sure what I'm doing wrong is anyone able to give me a start to finish how to tune it

Im not sure if I have to much water or dialing it wrong or? My return pump is a DC controllable so I can ramp it up or down as well. Maybe I have to many variables

Do I just set my return pump then leave that and mess with my overflow ?

It seems that the noise is mostly coming from the water falling into the overflow not slurping or gurgling from the pipes

Thanks a lot

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

[gregzz4]

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

[Craigdillman]

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)
