Silent and Failsafe Overflow System - Page 395

Lowering the valve will certainly help. What is the flow rate of the return pump?

Also, the discharge end of the siphon standpipe should be submerged .5" or so during normal operation.

This has probably been asked but there are thousands of posts and it would take forever to search for it, so I'm asking again sorry but I just picked up a used 75 gallon with a corner overflow (1" & 0.75" predrilled) is it safe to drill a third 1" hole to convert to a Bean? Image below, sorry it's not the best, I still have to clean everything.

2 problems. You can't get another hole into such a tight area and still have enough integrity in the glass and the bigger issue is that there is a strong chance that aquarium has a tempered bottom after it was drilled at factory so cannot be drilled again.
You can engineer something similar (2 drains, no emergency) using both existing holes as drains and just have your return over the top of the aquarium rather than through bottom

Thanks, after doing a bunch of research yesterday I was afraid of that. Didn't realize some manufacturers tempered glass after drilling till yesterday. I had that thought too, just running it without an emergency drain. I think my sump is big enough to handle the amount of water from the tank of there is a power outage but I'll have to make sure to have a high water sensor in the sump to turn off my return pump if my drains ever clog.

they call that the herbie overflow. It's still quiet just without that final added safety measure.

Folks... just an FYI, the site was down for a while.... back up now

Hope everyone is doing well.

Happy Reefing!

I want the siphon calculator back! I emailed you about that a while back

So a few notes:

If the flow volume is low and and the siphon standpipe is a very large diameter, then you are correct, the area between the valve and the sump may not product a true siphon. In this case submerging the end of the siphon (thus preventing atmospheric pressure from destroying the vacuum) will maintain the siphon. At higher flow volumes this does not become a problem.

We sometimes run into an issue at lower flows, where the volume is not sufficient to purge the standpipe of air. Drilling a small hole or two just above the (running) sump water line can fix this. The small hole will allow the standpipe to purge the air, but is not large enough to fully interfere with the siphon.

An alternative fix would be to place the control valve closer to the sump. This will ensure that he entire length of the standpipe (down to the valve) is always under full siphon.

Cheers...

Hi Bean...

So I'm running into this exact issue. I have a 300 gallon tank that I am running about 900-1200 gallons per hour through. It is plumbed with 1.5 plumbing in to the basement. The total length of pipe is about 50 feet with 15 feet of head.

Is one of the fixes preferable in this scenario? I would like to keep the valve closer to the tank if possible but also want to fix it correctly.

Thanks!

BeanAnimal · 03/07/2020, 12:20 AM

I would suggest submerging the siphon standpipe and/or reducing the diameter at the discharge end. You can reduce down a pipe size or use a valve. 1.5” at 15’ of head can move a tremendous amount of water.

Ideally, the adjustment would be at the sump end with this much head, but you can likely find a good balance by using a valve near the floor upstairs and submerge/reduce at the sump. Remember, tumbling water and cavitation make noise, a full pipe does not.

Thank you! I just looked at our respective stats. We joined Reef Central a year apart...I have 200+ posts...you have 20k+ posts and have set the standard in overflow design. Hats off to you!

And to think in the last 5 years I only have maybe 100 posts

I looked at one point years ago and the only folks with more posts were moderators... I hope that has changed!

In my opinion it is still the best system around.

Fragmented 99 · 04/17/2020, 06:32 AM

Need to silence a 250 reef ready with 2 corner overflows. Currently running a durso and return in each overflow. Wondering if I can convert one overflow to s Herbie overflow . Thinking the other overflow (durso,) could act as the emergency drain should the Herbie fail. Any issues with doing this?

Vinny Kreyling · 04/17/2020, 08:26 AM

Tony,
I run my 250 dual overflow with a Herbie in each & it's quiet. 2 - 1 inch pipes in each.
I come back over the top with 2 Sea Swirls

Fizbang · 04/20/2020, 07:29 AM

Hello all,
My beananimal question has to with the pump and ato side of things. I have the drains all setup and they are nice and quiet and function as they should. My main question is when I simulate a main drain clog the water in my return pump chamber drops a good 3" which, in turn, starts my ato. While the drains keep the system going couldn't my ato throw off my salinity a good bit? Is this normal operation or might I perhaps have something wrong?

Vinny Kreyling · 04/20/2020, 07:46 AM

When this happens it's normal.
The main pipe remains full & now 2 more pipes have to fill.
This has to come from somewhere & it comes from the pump chamber.
The only fix I can think of is a high water switch in the overflow to shut off the ATO & set off an alarm.

Hi..

I'm planning to build 8*4*2.5 feet (lbh) mixed reef tank..I would like to place the overflow box on 4 feet width side ..Can anyone suggest me on Overflow box size (inner and outer box) wich can handle the above size and Drain pipe size ?

I'm thinking about bean animal type overflow box..

Thanks in advance..

How much flow through the overflow box?

Are you sure? That tank comes out just shy of 600 gallons.

Sorry didn't get u but yes it's gng to be 550 to 600 gallons tank approx..

600 gallons tank with 20% to 30% Of rocks and it will be less than 600 gallons of water..

On the low side a 1" pipe with full siphon will flow 960 GPH.
IF you really want only 600 GPH that will do just fine.
As far as an overflow box I would look for reviews on a search here.

Sorry it's my mistake..it's 6000 GPH ..I LEFT ONE ZERO.. Extremely sorry...it's a 600 gallons tank..
