simplest overflow...

[hurricane_redbone]

I been readin all these complicated overflow systems on the DIY section and I really dont understand why people go through sooo much effort. correct me if im wrong but If I were to buy 2 really big PVC pipes and put them vertical at the back of the tank going straight threw the bottom and into the sump, wouldnt that work perfectly fine?. i dont get this wholeuber complicated crap. I wanna keep it simple. Would this idea work?

And also does it matter if I use really big PVC pipes or small ones? because i want to make sure than those pipes can carry the necesary amount of water in case i decide in the future to have my tank cycle faster...

the only reason to go with complicated HOB overflows is to keep from drilling the tank. A lot of tanks are tempered or full of water making it nearly impossible to drill. Drilling the tank would definitely eliminate the need for any other type of HOB overflow.

Even with a drilled tank most people don’t run straight pipes due to the noise
Durso style is what most do

And as far as flow rate I have never seen the #'s but a 1inch gravity drain pipe has some serious gph

The tank in question is a DIY plywood tank and is a perfect candidate for drilling the bottom. It is easier and cleaner to do it that way.

And we want some pictures of the tank progress

So my theory is right? I should do that?
If i put a large curve at the bottom going towards the sump, wouldnt that reduce the sound a lot?
