Silent and Failsafe Overflow System

[pdiehm]

We're running. 1" bulkheads, 1 1/2" piping. I had to adjust it once I redid my return, but about 3:15-3:30 we're dead silent.

I did it my build thread, but many thanks to Bean and Uncleof6 and countless others who have taken the time to answer my hundreds, if not thousands of questions, sometimes repeatedly.

Only issue I had wasn't getting the skim over the whole overflow box, but nothing a shim couldn't fix.

Works great, and have started the cycling process.

Congrats!

Rather annoying how water insists on being level all the time!

Shimming a stand/tank isn't something you can do with he tank full, so if you need to shim the tank, you should empty it and shim it now, before you start your cycle.

With how I built the stand, I was able to get some shims under the corner I needed. Being on carpet helped, immensely

Would the Bean Animal setup work with lower GPH pumps? Say 500gph?

 

[uncleof6]

Yes as long as you don't use monster bulkheads, use 1" bulkheads, and 1" pipe. Use 1.25" pipe for the open channel.

I will drill tomorrow my 40 gal. breeder. It will be mixed reef with 20 gal. sump. What size bulkheads and drain pipes should I use? Im thinking of drilling 3-1" holes for bulkheads. Siphon 3/4" pvc. Open Channel and Emergency line 1". Is that ok? Let me know, please. Thanks. Art

 

[Artur 1972]

I just saw post above. 40 breeder I look probably around 600-800 gal. turnaround. Is better to use 1" for syphon and emergency and 1.25 for open channel?

 

[uncleof6]

Good call.

So Im in the process of drilling my 40 breeder now. Do you think I can buy 16" long overflow somewhere for my tank? Or could I make it somehow? I spread 1" wholes so total for 3 holes is 12" so I need bigger box. Any good place to buy or should I go to Lowes and buy acrylic make teeth somehow and glue together? Never didi that before and acrylic doesn't bond good to glass, right? . Let me know soon, please. Thanks Art.

Bulk reef supply has one 18" long for 62$. But it is 4 1/4 deep. Maybe little too much..

If you have a glass tank, then you can use a glass overflow and use silicone which is very easy.

Hello all!
I'm new on reefcentral. I'm sorry, but my english is so bad. I hope you can help me. I will drill my 200 gal. tank this week. My first question:
These holes are in right place ?

I want to build a freshwater aquarium with sump for biological filtration. For my biofilter medias not necessary high flow, probably 600-800 GPH is enough, but MAXIMUM 1500. So I don't know yet. Between 600 and 1500 GPH :/. I see in this thread big bulkheads with low flow can cause problems in the full siphon, so 1" bulkhead is enough, but I'm confused about size of pipe. Uncleof6 wrote in 8255 1" pipe is enough for 600-800 GPH so it is clear. What do you think what is the maximum flow for 1" bulkhead+1" pipe? Must I use 1" bulkhead+1.5" piping for around 1000 GPH? And 1300-1500? The length of tube: 25 inches (vertical pipe). Thanks for your help!

How to do it with glass? Buy to pieces and silicon them together and then to back wall, coast to coast? Glass is heavy, what if the two pieces fall apart? Sorry maybe thats stupid, I just want to do it right..

This is off topic for this thread. It is not a stupid question, but it has been answered many times else where. This thread deals the drain system, not the construction of the overflow. At least not more than in passing. A new thread would be a more appropriate place for this question.

 

[Artur 1972]

Im sorry about that. I will try to find answer somewhere else. Im sure I will have more question right for this thread while Ill be going forward with my tank…

hey guys I'm new to reefcentral, i was trying to submit i knew thread but didn't know how to, but i have a question i am confused about, which type of overflow is the quieter one, and what is the difference and advantages/disadvantages of having one overflow box compared to two overflow boxes one on each side of the tank, I'm planning on having at least two drains and two returns, thanks.

1" bulkhead & pipe should be enough for your siphon to handle 800 gph. 1.5" pipe would be way too big. For the open channel pipe, it may be helpful to have 1.25 or 1.5" pipe, since the range of flows that 1" pipe can handle quietly before it starts to make noise is relatively small.

 

[Dice750]

Yes as long as you don't use monster bulkheads, use 1" bulkheads, and 1" pipe. Use 1.25" pipe for the open channel.

So a 1" bulkhead would be fine for the 1 1/4" open channel pipe?

Yes.

I'm in the process of building that overflow for my 40 breeder. Glass overflow 20x5x3 top will be even with bottom of top aquarium trim. Is that ok? And turned down elbows for syphon and open channel- what should be a distance to bottom of box ?
