Durso vs full siphon

[srobertb]

New Tank arrival in the next week or so. I have all the equipment for an E-Drain + full siphon via 2, 1.5” pipes that run 15’ down to my basement. Goal is 1,000gph flow on a 210g tank.

So I’m good with a durso based on the conservative figure of 1500gph through a 1.5” pipe….and fantastic with 2, 1.5” Durso drains. Why would I run a full siphon? It’s 15’ in my basement so I don’t care about noise. There won’t be any noise at the display, right?

If noise at the display isn’t an issue with the Durso, should I run 2 Dursos or a Durso and a slightly higher E-drain?

I’ve done full siphon with a gate valve before and it can be finicky so I’m wondering if I’ve over thought this and should just run 2 dursos.

The Durso will make some noise at the top of the stand pipe. How much it will bother you I can’t say. If you have quiet DC pumps you will notice it for sure though.
If you chamfer the e-overflow you should not have to mess with balance that much to keep it quiet.

My use-case is a bit different as the pumps are in the basement. They’re silent upstairs.. 1.5” pipes each running 1/3 capacity (500gph)

Im hoping someone with a similar setup (or larger) will comment.

Even 500 gph though a 1.5" standpipe will make some noise - whether enough to bother you, well only you will know that. Why wouldn't you run them in a herbie configuration?

I prefer full siphon but that’s just me..

Full siphon is silent... then... you will perseverate on the tiniest vibration noise from a powerhead instead. I think you will be happy either way, currently running full siphon on a BEAN. The only noise is from two power heads and trigger fish splashing water all over the place when they don't get fed on time.

1" pipe at full siphon drop 24" is 1700gph. 10ft drop would be 2500gph

I probably will run a Herbie. Everything is designed for it. If I can drop stuff (like the gate valve) I’m all for it. I have the gate valve and everything dry fit. Just pondering. I’ve never run Durso so I thought I’d ask.

Full siphon every time.
