PVC overflow

i wasn't sure where to put this.

DIY Overflow Using Only PVC Pipe (DIY OVERFLOW PROJECTS)

i'm planning on attempting this build. anyone ever tried it/ used it?

it looks easy and the theory seems sound.
any thoughts?

 

I thought about attempting one, but just got an overflow box instead with a U-tube. If you really wanted to, you could just have a vinyl tube doing into your sump. I looked at the diagrams before and it looks pretty good. I say go for it.

 

My only question is if little air bubbles accumulate you would have to have the airline tube connected to a powerhead just to make sure its always air free. I would def. build one if I saw one in action. expeccially in power outage situations.

 

http://www.3reef.com/forums/i-made/nice-cheap-diy-overflow-29396.html is the one I see lot of people check out. Never tried it myself, I would rather drill a tank.

 

I've built two of em in the past. They work perfectly. Very simple to build.

 

i think i will try it. i would have it permanently connected to a power head. thanks for the input everyone. good to hear from someone who has already done it.
i would have preferred to drill the tank, but i didn't plan on having a sump and it's too late now.
i will let u know how it goes.

Cool.
Keep us posted

 

I built one, didn’t work.

 

what kind of flow should i aim for to my sump. i have an 80g tank. the sump is about 50g.
would about 250 gph be enough?

 

do you have any idea why?
