Silent and Failsafe Overflow System

[BeanAnimal]

Joey,

some people have diverted some or all of the siphon flow to the skimmer. Fluctuations in skimmer level will however alter the overall flow of the siphon. Also, in most cases, the siphon flow is far too much for the typical skimmer. You may only want a small portion of that flow going through the skimmer.

thank you BeanAnimal

bean,

is it possible to just make the emergency and siphon pipes elbows instead of sanitary tee's?

it's going to be airtight anyway.

just the open pipe will be a sanitary tee

thanks

joey

Yes, the siphon and emergency can be elbows instead of tees. I prefer to have access, but you may not wish to (or need to) access the inside of the standpipes.

allright

thanks bean. you da man!

I just plumbed 240 with the fail safe overflows and let me tell you it is so easy to adjust and it is quieter than my 30 cube. Thanks bean

Your welcome bruce! I am glad it worked out for you.

Hey Bean and others,

Thanks for this thread! It's great info.
I've decided I want to set my coral prop tanks up like this. Luckily, each one has three bulkheads in it already. Each tank is 6 ft long and 70 gallons. The problems are

1)The bulkheads are not all together, one is on the right and two are on the left (reverse on the other tank, see pics)
2)The bulkheads are different from the one on your site/this thread at least to the point where they have a 90degree fitting for tubing to go onto. The 90degree bend seems to be glued to the bulkhead and the bulkheads themselves are siliconed to the glass.
3)Continuing from (2) above this is stainless steel enforced tubing, and is expensive. I would like to reuse it if possible.

The tanks both came this way, but I am trying to use what I have. If possible I would like to stray away from removing these bulkheads since as previously mentioned they are siliconed in (No idea why) but the 90 degree bends seem to be in my way. What should I do?

Also with regards to the overflow box, I was thinking of two boxes on each tank instead of one box that runs all the way across. They would be 3" x 3" x 23" long each, one on each end of each tank. Here is my tanks currently and thanks in advance for reading.

wow where did you get a tank like that with those dimensions??

 

[MperRluvR]

Bought them from a guy. They are Perfecto tanks I believe. 6'x18"x12" high, basically a 135 cut in half.

All,

I am having an issue tuning my failsafe and quiet overflows. Is there a trick to this? I am using a ball valve to adjust the flow.

 

[2_zoa]

did you build it like the picture or do it differently? how big is your plumbing? How big is your pump?..........

 

[chetscc]

Yes, I believe I built it like shown. I am utilizing 1" plumbing until I get outside of the tank and then going to 1.5" plumbing. I have a mag 18 with a squid on the return.

Bean,

I am in the process of setting up a 210 gallon tank. It has Four drilled holes in the bottom of the tank (see pic)

Anyways.... I am going to follow your lead on the overflow design. Thanks a TON for posting this for everyone! Anyways would you suggest 1" holes like you did or would you go larger for this tank? It is 7x2x2... Also, I am planning on using the 4 holes in the bottom for Closed Loop(which I have never owned before). They are 3/4". How many more holes would you drill (if any) for the closed loop and where would they be?

Do you have any pictures of your tank fully setup?

The return pump is going to be a Mag 24 (since I already own it) but I can switch it for something else if recommended... I am relatively new to salt water.

Hey Bean --

Looking at the design of the overflow box, is the overflow the entire length of the tank? Also, how big are those pieces that you have there? They look to be about 5" wide on both of them, but I could be wrong. If so, please correct me on that.

Also, is the overflow a DIY as well? If so, is it acrylic that you used? It doesn't look like it's cut with teeth in it, is that correct?

Thanks for a great design.

As that sounds really great and all, but my poor eyes have gone to mush with all 35 pages of this thread. Which is why I have opted to ask to just clarify .

I'll help out a little here.

Yes the overflow spans the entire length of the tank.

While I can't speak for Bean, the overflow I constructed was 4" wide x 5" tall... yes it is DIY'd.

No teeth... smooth egde... I actually prefer the smooth edge.

I constructed 2 of these systems.

This one was 48" long x 4" deep x 5" tall out of 1/4" glass pieces I had cut by the local glass shop. I didn't span it the entire length because it was a 6' tank and felt that 48" would be sufficient. Also, I constructed the overflow box outside the tank, before installing it in the tank.

Here's the back of the tank :eek2:

Here are 2 pictures of the coast to coast one I made... same dimensions. I didn't take a whole lot of pics during the consrtuction, but I think there's enough to get the basic idea. This one was constucted inside the tank.
