Overflow too loud need help!

[Supreme Reefs]

Its a 90g with a built in overflow, just the regular reef ready kind with the generic overflow kit. I have set this up in the past but that was a very long time ago and i dont remember it making so much noise. It gargles a lot even though theres an air inlet on the top of the drain part. Anyone experience this before or have any suggestions?

Also the pump is pretty strong it pumps around 1400-1500gph (could be less), not sure if that matters though.

get a smaller pump... 14-1500 is alot of flow through a standard overflow. I would shoot for the 300-400gph range, you dont need alot of flow through your sump and this will save you in heat, energy, and noise

mine is loud as well.. :X. I just got some sponges in there to reduce the noise, but it's still loud. Bad thing is that i had to get used to it because it's in my bedroom.haha. terribleee!

 

[Supreme Reefs]

aw man i think its too late to go with a different pump right now... i already did the plumbing

Any other way i can reduce noise?

Ah that sucks :/ how strong is your pump and how many gallons is your tank?

I had the same problem. It is from too much flow from the return pump. It overwhelms the overflow box, causing it to gurgle and gush. I just added a ball valve in front of the pump, and slowly increased the restriction a little at a time, until the gurgle sound went away.

Good luck.

By adding a ball valve after the pump, you will actually shorten the life of the pump by restricting it. Instead, put a T in the return line, with one pipe going up to the DT and one back into the sump. Put a ball valve on the one that returns to the sump. If the ball valve is completely open, it will return all the water to the sump and if it's completely closed, it will send it all to the DT. Play arond with the valve until you get the flow rate you'd like.

This is simply not true. If you put a ball valve on the the output and reduce the flow, the motor does less work and has less wear on it. You can hook a pump up to a watt meter and when you reduce the flow on the output it actually draws less watts. Even contact any manufacturer and they will tell you it is OK to restrict "OUTPUT". Input is a different story and if you restrict that, it can actually damage the pump.

Paul is correct +1

I use a gate valve vs. a ball valve to more precisely adjust the flow back to the display, but either will work.

I have a 1500 gph Pan World and have it dialed back about 50%. I plan to add more tanks to my system and wanted the extra horsepower for expansion.

You need to set up a durso pipe like shown above... I run 3000+ gph threw my sumps on my tanks I love the flow and my skimmer loves turnover.... Do a search for durso standpipes if you build it excatly like they show it should be dead silent... Like I said I pull over 3000gph with 1" bulkheads of all things and my system is dead silent... People don't believe it when they see it...

Wow thanks for the replies everyone! this is very helpful. I cant modify too much on the drain since i dont have too much space. I like the durso idea and ball valve, does it matter how far after the pump i put it?

Heres a pic of how the pump is set up, not sure if you guys can see it.

I was thinking about putting a ball valve in the middle where the clear tubing part is. Would that be ok?

Also anyone have a pic of how they made their durso stand pipe?

 

[Supreme Reefs]

Anyone would know if that is ok?

I am leaving soon to the store to pick up some parts...

 

[Coralgasm]

drill two holes in the standpipe

 

[Supreme Reefs]

BTW this is what my overflow kit looks like

All Glass Aquarium Overflow Accessory Kit - New - AAG29251

I guess it has the same concept of the durso so wouldnt it work the same?

 

[Supreme Reefs]

drill two holes in the standpipe

Mine has 2 holes also on the side at the top, what do the holes do?

 

[Coralgasm]

aga tends to be loud, heavy slurp or constant peee?

 

[Coralgasm]

the standpipe is telescopic, not that it matters much, but in relation to your overflow, how high do you have it set?

 

[Supreme Reefs]

My aga i set it high and low since its adjustable so i can see if that makes a difference and its still the same. Slurps a lot...

 

[Coralgasm]

Slurp usually means too much flow at intervals, what pump?

 

[Supreme Reefs]

Im thinking about getting a gate valve or ball valve at lowes soon, so if i connect it right before the clear tubing starts (from bottom up) would that be fine?
