plumbed in my own tank, need help with noise from overflow

[shamoo]

Hello all,

I've been in the process putting my tank together for the last few months. my tank (150g) only came with drilled holes at the bottom of the tank, so ive plumb everything in myself.
through reading tons of post on here and youtube i've set up my tank and pretty happy with it. i have teasted it, so if the pump trips or power goes out the water will drain down into the sump and not overflow. i have got 2 overflow's in the main tank, 1.5" that "Y" into a 2" pipe. Reason being if one gets blocked the other pipe will cope easily, or if something blocks it and gets through the 1.5" it will be impossible to block as it goes into a 2" pipe. Currently i am only testing the water flow but the noise from sump is too loud. Currently the sump is not enclosed and will be in the future once everything is set.
The sump overflow return splits into 2 pipes, i am going to put filter socks on them hoping this will solve it, i have yet to buy the socks, But there is a lot of water returning into the sump at force.
I dont want to turn down the return pump as that dictates how much water is cleaned, do you have any ideas how to ease the force of the water returning into the sump?
in the pictures, the Y is my overflow and the black caps are acting as a grill that will be fitted properly, this is really helpng with the vortex sucking noinse/motion. The T is my return feed which have drilled holes to act as a jet if needed also i will be putting on open elbows on the ends to direct the flow of water to act like a power head and get the water moving.
please any advise will be welcome

I would say your best bet is filter socks

look up reverse durso, it quieted mine down significantly.

If you can, change the 90's for 45's. That will help some. I'm assuming these drains are Durso style? If so, adding a "T" fitting just above the waterline in the sump will help as well. Place it so that the "leg" of the T is above the water to allow any trapped air to escape before the water enters the sump. You will also be better off to use totally separate drains rather than combining them. Although I understand your logic in doing so, 1x2" does not equal 2x1.5".

Personally, I can't stand filter socks. They are just one more thing to clean, and in most cases, really are not needed. My 120DT uses no mechanical filtration at all, and I am far from alone.

If there is any gurgling/flushing noise from the drains, it is because there is too much flow for them to handle. What return pump are you using? IME, the easiest way to quiet down a Durso drain is to reduce the flow going into it. That is easily handled with a valve on the return line from the pump going to the display. Circulation in the tank is best handled by in-tank powerheads of one brand or another. Total flow is dependent on exactly what you plan to keep and is a combination of the powerheads and the return pump. In my SPS dominated DT, I have at least 80x turnover provided by my return pump (eheim 1262) pushing maybe 500gph with the rest supplied by a pair of Gyre 250's.

hth?

Faulty logic.


You do not need that much flow for a sump. Its not all being cleaned.


I use a 90 below the surface to help with noise

Your system 300gph is more then enough, hell its all that's needed for most.



I have about 300G total volume with a 100G basement sump and I'm running 500gph and my 2 1" drains were insulated because of noise.

I did something a little different, it helps with both the bubble and the noise, although you can still hear it some.

I took a piece of 4 in pvc, drilled 2 inch holes around it, then cut it so I ended up with half circles (this is going to be the bottom) then I cut it to height so that is was above the normal water line and above where the drain lines enter (they stick down into it). This sort of traps the bubbles in the 4 in but the half holes in the bottom allow the flow out.

I can't remember where I saw it but want to say its not my idea, I copied it.

YMMV

Hofer Gurgle buster?

This is the reverse durso I was talking about. I made it longer to go into a sock
