Herbie Parts?

[tidus10]

So in just got my Synergy Reef - Ghost Overflow in, its cool I like it, but I would like to run the Herbie system in it since it has 3 1" bulkheads in the rear box.

I want to make sure I have the correct parts needed to do this correctly and I have an understanding of what I do.

Since there are a million different designs out there some with the air line and some without, do i need the airline?

And pretty much, the center bulkheads gets a straight pipe up higher than the other 2

The other 2, one is higher than the other by like a 1/2" or so and they are both are U shaped facing down towards the bottom of the box.

Do i need the airline? and Do i need that gate valve thing to slow the rate through the full siphon drain? Do I need 1 or 2 gate valves?

I'm not exactly sure what you mean by an airline. You will need an open to the air port, but not something that is hooked up to an air pump.

You can use either a gate valve (more expensive) or a ball valve. The gate valve offers finer adjustment, especially when dealing with 1" pvc. And yes, I would get 2 valves.

My other piece of advice is to find a plan and stick with it, since this is your first build.

This photo shows the air hose that comes up and around. i didnt know if that was needed on one of them.. but I think I have a plan and im just trying to get as much information as possible before I start glueing PVC...

Since the Bulkheads are slip to slip is there any way to NOT glue these together? or since its a slip to slip bulkhead there is no way to seal it without glueing right?

You are looking at a Bean Animal. The air-line is needed and allows the open channel to go into full-siphon mode if the main full-siphon fails. Otherwise you risk flood since a full-siphon can flow a LOT more water than an open channel.

read the site you got that picture from it explains it all.

I know that the picture was from a Bean animal setup.. I wasnt sure if I needed that with a herbie setup.. these two are kinda close...

im asking for help here about the Herbie style

Herbie only uses two drains; bean animal uses three. Herbie is a siphon and an open channel; airline is not necessary.

So when i have 3 channels its instantly a bean animal? Two siphons and 1 open?

 

[ca1ore]

Right, using a third drain makes it a bean animal design. Third drain is a hybrid siphon/open channel with the airline functioning to switch between the two.

and thats why i asked...

So then i have the bean animal site open i thought that Herbie had the 3 channels at different height..

How do i attach that air tube to the PVC? drill and tap?

 

[ca1ore]

Do it like the picture you posted :lol:

 

[fishgate]

Glue on a cap and tap it for a john guest style fitting. The tube wraps around and is just above the water line so if the water level rises, it covers the tube and the open channel can become a full siphon and take the load of the normal full siphon.

Bean = siphon, open/siphon and emergency. Herbie runs without an emergency drain. Bean fixes that design flaw.

No, but Bean's website does, as does Fishgate's post.

Beyond this, from your previous posts, you seem to have an incomplete understanding of the bean and herbie overflow systems. Before you go any further, I would re-read bean and Herbie's descriptions of their systems, make sure you fully understand what you're building & ask questions about what you don't understand. I'd hate to see you spend a lot of time, money and effort going down the wrong path.

1,000 words of it, including the answer to your particular question. Not sure if you are trying to be intentionally obtuse, but go read the article from whence said picture is sourced. It really does provide the whole story ..... along with lots of nice pictures.

Google's not always right - the picture's of a bean animal overflow :spin3:

Bean's web site has lots of other useful stuff on it as well.

Actually the Herbie uses a siphon and an emergency, assuming it is running right which in my experience was almost impossible to do. That is why I have a Bean running on my 130g now and it works flawlessly, as designed. I agree with what is said here...make sure you 100% understand what you are doing with it before you dump a bunch of water all over the place and spend lots of money on PVC. Those parts may be $1.29 but it is amazing how fast they add up.

Not to mention the gas required for those 5 trips to the hardware store.

Only 5? I usually end up with 10!:headwallblue:
