Silent and Failsafe Overflow System

[ThrowinRoost89]

aahhh


ive only had my 120's sump running for about 2 weeks now and i have not actually checked if my emergency drain would handle the mag 12.

sooooooo, i just tried it.
i have the 2 1in emg drains T'ed to 1 and then into the sump. so i closed both of my gate valves and they handle the mag 12 no prob. i plugged the top of one emg drain with my thunb and the water level started to rise, and when i pulled my thumb out the water level went back down in a couple seconds.

but it that would only happen if both drains got plugged at the same time.


i would think you would want you EMERGENCY EMERGENCY drain as loud as possible, so you know s___ is rolling down hill quick lol

Count me in on any campaign to get back Bean.

For Those In Need Of Their Daily BeanAnimal Fix

Looks like the BeanAnimal has intentions to continue his critical, provocative, and often intelligent dialog of all things DIY. Maybe he will add a discussion forum soon. (wink-wink)

http://www.beananimal.com/about.aspx

Personally, I hope that it becomes a popular hot-spot for critical analysis and lively debate/discussion among like-minded enthusiasts. Something sorely missing in our current P.C. culture.

Yeah, the signal to noise ratio has dropped dangerously low. Thanks for the link.

thanks for the link. i miss BeAn Animal and i really would like to know if he's taken up residence on another forum, as i would follow him there. WRT hosting your own forum -- that is an awful lot of work and consumes an awful lot of bandwidth. BTDT.

Agreed.

I figure Mike H. will let Bean back in soon, but I think that Bean is way to big a fellow to be taught a lesson and most likely the Ban will mean that he will never participate the same way.

I really think the Mods should take a bit longer before banning A+ posters like Bean and Grim Reefer. Grim was never the same after his Ban, he just never seemed to be as enthusiastic about helping people and I fear that is what will happen with Bean if he returns.

I've set up several of these PHP-powered forums for clients before. There's not much work involved in doing so.....until the membership gets huge, like it is here at RC.

 

[hyperfocal]

Yeah, ironically it's the moderation that's the real work.

I dont know if you guys can answer this question but does it matter how close together the bulkheads are. I am building a 8' long tank and i dont really want them to be right next to eachother could they be a few feet apart?

I dont think it matters so long as they are all feeding out of the same overflow box inside the tank.

i am going to try this on my nano setup before i implement on my 260g... i hope all works well...

 

[jimnrose]

I'm new to the hobby and starting a 125 gallon reef tank. This thread is a great idea on how to design an overflow box including a lot of work by the author to describe the detains.
In my case, access is limited to one side of the tank and I'm thinking or having the water return (400+gph) via a manifold (1 1/4" pvc pipe)above the water line. Does this make sense????

jimnrose,
Welcome!

Yes To have the return line above the water line is fine. Do you mean up and over the side of the tank?

I dont care for having the actual water outlet above water due to noise and splashing, which creates salt creep (buildup of salt crystals on dry surfaces).

When you put the outlet nozzle under the water, you must drill an antisiphon hole just below the water level. This way, the tank will only drain down to that level when the power goes out, or the pump stops.

You may already know this, if so great.
HTH, and let us know how your installation goes.
Chris

The only two options I have is to either come back into the display uner the overflow box or go over the side and come back to the water level (via fittings). I didn't like the first option because the bulkhead fitting would be very low (to the water level) and if a leak developed I would loose a lot of water, etc, plus the reefs would interfere with the return distribution pipe. Sooo, I left with coming over the top. I could add drop lines (fittings) thereby having the entry points below the water level therby avoiding the noise, splashing and salt problems. Does that make sense?
I just ordered the tank (125 gal: 72x24x17) & now plan to order the PVC fittings. It's time to spend.
Thanks for your inputs Chris.

I don't know if this has already been asked (read the entire thread--several times--before), but.....will drilling the three holes compromise the structural integrity of the glass?

I have a 55G made from 3/8" glass. What are everyone's drilling recommendations?

 

[BeanAnimal]

Drilling three holes should be fine. It is a good idea to keep the holes at least 1.5 diameter apart.

Be careful, many 55 gallon tanks are reported to have tempered sides.

The only problem I see is that a 55 gallon tank is very narrow and does not allow much room for an internal overflow AND room to get light into the tank.

You may consider an internal overflow box with a very narrow profle that feeds an external overflow box and the standpipes.

 

[jimnrose]

I'm planning on drilling 2 3/4" holes thru 3/8" acrylic with only 1 3/8" spacing. I haven't done this before and the tank is still 'on order' but plan to purchase a new cutting bit. If anyone has drilled large loes thru acrylic and could please give me guidance I would appreciate it.

 

[BeanAnimal]

You may want to check with Acrylics here at RC regarding the hole spacing with acrylic. I don't see that it will be a problem. Acrylic can flex a great deal before it fails due to stress. Glass is not so forgiving and a small crack quickly becomes a large crack.

You will either want to use a router and a template or a holesaw. If you use a stnadard holesaw, you will need to cut very slowly and use a good deal of water to keep the tailings out of the kerf. If they are not removed they will melt and the saw will get stuck.
