Bean overflow with a Aqueon Megaflow

[Cobrasvt1999]

Hello all!

Thanks in advance for the help! So i got my hands on a really cheap Aqueon 180 tank thats pre-drilled and equipped with the laughable Megaflow.

So im trying to figure out how to setup a completely silent overflow with either a herbie or a bean animal style system. Each of the 2 towers have 2 holes drilled in the bottom, so im thinking about returns coming up in each of the 2 towers and one tower would get a complete siphon while the other is a wet emergency overflow in the other tower.

Does this sound doable? any other ideas? I really dont wanna drill the back of the tank, but im still half tempted to plug the 4 bottom holes with bulkheads and drill a new weir into the back...

Thanks for the advice!

I suppose I could also use all 4 overflow holes for the full bean animal return and drill 2 return holes in the back panel?

1 full siphon on each joined by a gate valve before it hits your sump
1 half
1 emergency

I like that idea. Then drill the return lines in the back?

Side note, How much water can a 1 (1 & 1/4" ?)inch pipe in full siphon actually move? im sure the answer isnt simple because google certainly dosent give a simple response to that question...

Some of the plumbing gurus can answer better. You will get a surprisingly large amount of flow thru 1 inch pipe. As long as it drains without a bunch of level sections and as few turns as possible. You can also use 1 1/2 pipe everywhere except the bulkhead.

sounds good. the bulkheads are fitted for 1 inch pipe, so I figure I would continue to use that, however, where the siphon joins together just before the t I would increase the size to 1 1/4. thats the largest size that the roller matt I have decided to try can accept.

not a bean overflow, but i recently re-plumbed my megaflow with the gurgle buster design and it is very quiet. My tank has a basement sump also, so I am actually quite surprised with how quiet it really is.

gurgle buster? havent seen that design yet. would you say that its completely silent or can you hear some sound from it?

With my setup, all I hear is water trickling down the overflow and through the pipes. My vortech's dryside is right around the same decibel level, if I had to guess. I'm sure with a more standard set-up of sump under display, it would be even quieter. I have a basement sump so I'd imagine some of the volume is the water falling 10 foot. haha

Edit: A full siphon would most likely get rid of even more of the water trickling sound. I could try and take a video for you if you'd like.
