What’s your Favorite Overflow Method?

[rdnelson]

Should be picking up my new 125 today. The tank is not drilled so I have many options available. I am not sure if the bottom is tempered or not but understand that if it is a Durso is out of the question. But, assuming it isn’t tempered, I would love for you experienced people to chime in with what you think is the best option and why. As of right now, I am leaning towards a coast-to-coast overflow box with the Bean Animal style drain. I really don’t want to go with a HOB overflow unless I have no other option. I also would love to hear your ideas on the return. If all works out, I am thinking of doing a closed loop to eliminate the need for power heads. I want this looking as clean as possible.

As always, I appreciate your help.

BEAN. Simi Coast to Coast

I will be doing a bean soon. got the tank lastnight and i have seen the bean in action. by far the very best way to get water out of the tank. flow is great and the only sound i could hear was the humm of the return pump

Have both styles a Bean and a standard overflow I really like the Bean. Couple of reasons why..... Bean, dosent take up floor space, has safety measure to prevent possible overflow due to clogged pipe (which btw has happened in my single drain standard when a snail crawled into it) I can run one pipe to my skimmer compartment in my sump and one directly to the refugium, silent, excellent surface skimming, I could probably think of a few more but I am still working on my first cup of coffee. Drawbacks... about the only one I can really think of is that mine does not have the teeth cut into it so I think algae build up that may be a problem in the future since I cant put a cover on it to black it out and no water pulling from the bottom up so I have to keep some good flow on the bottom to get the stuff up into the overflow box. However both of my tanks are BB so that is not a problem.

All my research points to bean animal. Quiet, less tank space required, good surface skimming, and safety of overflow... May be even more reasons.

I'm just curious to know how you think the dual overflow compares to the bean? My tank has two "overflows". One is your standard setup but the other actually draws water from the bottom of the tank. It then rises and goes down the standpipe. From a safety standpoint, I think it's just as safe. If one pipe clogs, there is another.

I will say that the quiteness of the bean is something to desire. My only question is how do you add one to an existing tank? The only bean animal's that I have seen have been on acrylic tanks, not glass. Giuliano's for example.

Or does the "bean animal" design really just refer to the use of a full siphon backed up by an emergency pipe, and not so much the coast to coast box.

I have the coast to coast and the tank and overflow are both glass. Silicone holds it all together.

Mine is all glass, except for the overflow. I guess you could use a tank that is drilled. You would have to plug off those holes and drill 3 new ones on the back. And build the overflow. It would look better to just get a non-drilled tank and build it.

If u have two ridding already you could drill one more hole for the emerge. Drain and then take the air tube off of one and add a ballvale . Then u will have a full siphon w/ ballvalce one w/ ridding and a inherit emergency drain .
Do you have two returns you could convert it to your emergency drain

Edit: well gotta love auto correct

durso not ridding. dont ask me how it changes after you hit the send button. oh and other words LOL

 

[eagle9252]

simple...
this is something I did to cover the HOB overflow. you can take acrylic and bend it to have say a 1/4" opening and it could have a brace in the middle with all of it open it's better than the teeth anyway. then you can paint it black and cover up

Today I did the work and picked up the tank, stand and canopy as payment. The bottom is tempered so that decides it for me. Bean Animal it will be. I will build my own semi-coast to coast over flow. Seems everyone wants $20.00 per hole to drill the tank so I will buy my own bit and do the drilling myself. Should save a little but more importantly I can the drill tanks for others. ;-). I was pretty set on the Bean to begin with but I wanted to hear what all of you thought about them. Thanks for all the input. I appreciate it.

You can buy one of these ..

It will just about be spent after 3 holes. I ordered from them and it took about a week and a half to get here.. The one above is for a SCH 80 1.5 bulkhead.

I had a bean overflow and loved it, it did take a while to get it properly tuned in.
