Silent and Failsafe Overflow System

BeanAnimal said:
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!

Still in the hobby, just busy.
 
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?
 
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?
 
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..

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.

How is one the safely incorporate a roller mat into their bean animal overload design given that the roller mats seem to require that they be feed off of the main drain?

I ask this as my understanding is that the termination of the drain lines for the bean animal designs are to be just under the water line by an 1" to 2 inches.
