I am looking into a new tank 250 gal. I have talked to several people about overflows. What is the pros and cons of a external overflow?
I have had one person tell me they are no good, and one says they are the best. So now I am stuck what to do?

Thank you Bruce

It provides more space inside the tank.

So that would be a PRO. Do you know of any disadvantages?

Cons:

-Cost of more glass and labor
-extra space
-Bigger stand, maybe (depends on design, not required but gives more space so why not)

Just off the top of my head. There are plenty more I am sure, come on with the EXPERTS, educate us.......Please.

Internal or external, the only difference is one is inside the tank and one is outside the tank. External gives an unobstructed viewing areas in the tank.

Hang on overflow box is an entirely different ballgame, is it possible they were thinking of this when they spoke negative?

Thanks for the input . Now I just got to decide if I want to go through with this. I say yes wife say NO. Any one want to buy a Wife?

I have heard that external is much louder!And have been told that built in overflows are better.But what do I know Im just a rookie.

I doubt space within the tank will be an issue on one that large..

I'd stick to internal, personally... (every glass joint is another opportunity for the tank to fail..)

(I assume you're talking about an external, tank constructed overflow, not an overflow box)

yes.

if you're worried about "in tank real estate"..

consider a coast to coast internal overflow.. (it wouldn't have to be more than a couple inches deep X a couple inches wide... )

I just ordered my tank about 2 weeks and ended up going with internal overflows, its a 72x30x24. I was going to go with external overflows but my fiancee really disliked the look of the tank being set out from the wall. The more I thought about it, the more I started leaning toward the sleeker look of the tank being against the wall. It is really just a preference thing.

That is the size I am looking at also.

Aah cool I noticed you dont live far from me, I am from dalton. Are you looking to get a glass or acrylic tank? I found this tank on craigslist the other day and with It had been for sale before I ordered mine. It is a little smaller than the one you are looking for but its a really good price if you are looking for glass. http://atlanta.craigslist.org/sat/for/2275535930.html

Glass, I have an acrylic one now. That does look like a good price.
