NEW plumbing method for an ULTRA QUIET REEF TANK!!!! LONG !!!!

[DogueDeBordeaux]

Brycntif, that is good to have the emerengcy drain bigger than the full siphon drain. If the 3/4" full siphon drain gets clogged, the 1" emerengcy drain will handle it.
The 1" drain can not drain more water than the pump pushing the water back into the tank. So, it can not over flow the sump. It will just make the toilet flushing noise until you get the 3/4" drain flowing again.

So how would you run this in a dual overflow tank? My tank is a 4' 120 with dual overflows that each have a 1" and 3/4" hole.

I would use the 3/4" as drains. I would plumb them seperate with 3/4" gate valves, the Tee into 1 1/4" to the sump.
I would use both 1" as emergency (open) drains. I would plumb each seperate to the sump.

Using two 3/4" gate valves is a lot easier tuning the drains.

On the return I would just use something like a seaswirl.

Well I finally got my tank set up for a water test with the Herbie and it worked perfect with the 3/4" full siphon and 1" emergency. I tested the the emergency by placing my finger in the 3/4" drain and plugging it and the 1" was easily able to handle the 500-600gph my return was pushing and as DogueDeBordeaux said you will know if your main drain is ever clogged by the sound from the emergency in full use. Thanks!

It has been awhile since I have been on here and I am currently beginning the setup of a 150 reef. After going thttp://www.youtube.com/watch?v=Cbh14k2oMd8&feature=relatedhrough 20 plus pages of this thread still did not get a clear image of the bernie setup. Is this you tube video it in a nutshell with an extra non syphonned drain line? Also would I need my drainlines to be 1.5"

Hello, is there any reason for me to use "Durso style" pipes in my overflow box. I am setting up a Herbie drain and was thinking about just using two open pipes but if there is a benefit to adding a T and 90 on top, will do so. I don't think I can glue these though because I would not be able to unthread my stand pipe from the bulkhead. There is not enough room in the box.

Thanks!

Sorry, double post.

You must have an open channel (dry). The other will be gated to create the siphon. The dry is the emergency incase the siphon ever get blocked.

Thanks, yes I understand. I have not yet placed my stand pipes in the overflow. I know that my main will be gated and fully submerged in overflow water and the emergency will be slightly higher for protection. My question is - does it matter if they are both just straight pvc pipe with no elbow (just an open top) or is there an advantage to making them look like dursos?

THanks

In this setup I don't know of any advantage. It might cause the emergency to run quieter, but then you don't want that to run quietly - you want it to set off bells and whistles.

Just wanted to share how Herbie's idea helped me silence my noisy overflow drain:

Well I went thought about 10 pages of this thread and decided to try it out, but have a few questions if anyone could help.

My questions would be:
(My setup: 75g RR tank, Mag 9.5 return feeding 2 reactors probably 450-600 GPH delivered to tank if I had to guess fed on 3/4" pvc)

1. I have a x2 1" bulkheads but one has a 3/4" reducer glued into it.
I came across a calculator for full siphon flow rates and it looks like 3/4" can handle a lot of flow. I'm going to run 1" pipe for both, but should the 3/4" bulkhead be my main? and the 1" bulkhead be my emergency?

2. Are there any problems running the main drain pipe long? or should it be as short as possible? guessing it would not really matter.

3. I see people use strainers and 90 deg. fittings on the stand pipes, then I see others just using bare pipes. Which is better?

 

[TheFishMan65]

Well IMHO

1) Use the 3/4 for the siphon - then if there is a problem the larger drain should be able to handle it
2) Horizontal is the problem since it is harder to get the air out. Use 45 to try and avoid horizontal. Longer vertical will flow more water, but the valve should be near the end to avoid cavitation.
3) Who is likely to get into the pipe?

 

[h2hiero]

Can the 3/4 hose on the returns go 1800gph atleast?

 

[TheFishMan65]

Maybe with a 10 foot drop.

not trying to hijack this thread im trying to find a way to reduce the noise and the bubble in the sump that do not have a baffles and dont want to lower the flow on the return pump because it the only flows in the 40b right now.

the overflow is in the middle the left and right are the return

i just got vinyl tubing on the inside of my filter socks (the longest filter socks possible) and tube inside to the bottom deep in water makes it go away.
