Very nice. Super clean set up. Following along

Will the overflow still be quiet and silent with just a stand pipe and a strainer on top? Don't you need to have it capped? Pardon my ignorance on how beananimal overflows work.

The gate value will hold the water back therefore falling onto itself making it quiet

You are correct. This is not a typical bean animal overflow. This is set up more like a herbie with another main drain.

See this website for a true bean animal

With a strainer at the top of the open channel pipe, wouldn't air get in regardless of having the gate valve holding the water back?

Thank you for your comments, I am still a newbie at reefing, I started with a 20 gallon long tank in May, I am still learning about overflows, when I design the tank and overflow, I made it so I can make changes, this is in my living room so I wanted to keep this dead silent, so is this what I will need in my main drain?
Do I need to drill and tap the pipe to put a fitting in?

All my 1.5" bulkheads are slip

Does someone in Edmonton have a Beananimal setup? that I can get some advice from? Thanks

Don't get caught up trying to replicate the bean to closely, you got the right idea just need a little tweaking.

You have two options, convert to straight herbie or a modified version of beanaminal.

For Herbie:
Change the drain with the ball valve into a second back up just like the center drain.
Now just use the gate valve drain to adjust overflow water height just below the two back up drains. Be sure to test it with gate valve fully closed to insure the back ups can take full flow without tank overflowing, shouldn't be an issue but some make the back up pipe(s) too high.

For Beananimal
Change the drain with the ball valve to standpipe, durso, stockman or HGB, doesn't really matter but durso is more common.
The height of the standpipe needs to be lower than center back up but higher than primary gate valve drain.
You adjust gate valve so you get a little flow through the standpipe, with a small amount of water flow it should still be quiet but in theory not as quiet as pure herbie.
The advantage here is the system is more flexible, flow rate can change slightly and it should still be quiet, basically less need for periodic adjustment.

Here's a durso pic for ref.

Thanks Sphelps

From my understanding I need 2 of these, one with a hole on top drilled and fitted with a pipe, the primary is a complete siphon, how low should the pipe be?

I just turned the pipe towards the outside for a better photograph

FYI: the other side I have a ball valve, the open stand pipe is in the center, because I cannot reach the center once the tank is in place

Nope that's not what you want. I'll draw a little picture for you in a sec.

This should be more clear, it's basically beananimal which is a herbie overflow with an extra drain and a standpipe.

You can set the operating water level height by the height of the standpipe, it's low in this example but it gives you the idea. See previous durso image for standpipe details.
