Overflow help
 

I am new and trying to get advice on drilling and making my own overflow. please help :sad:

Hi

Internal or external?
Tank size?
There are a lot of variables...

That said, look in "bean animal overflow". It is totally silent and flood-proof.

My tank journal might be some help? http://www.canreef.com/vbulletin/showthread.php?t=92064

Cheers

I did a 4' wide "Bean Animal" overflow on a 6' 200G and love it. Only thing I wish I did differently is make it external. Silent and safe.

20h, and I was thinking internal. What can I use to make a overflow?

Most of the internal ones I've seen use glass to enclose a corner, and have a black acrylic sheet siliconed to the outside of the glass with the fingers cut in the top to prevent fish from going into the overflow. If you google reef ready tanks, there will be lots of examples. There's lots of types to choose from.

I was also going to suggest this, sounds like a good route for a tidy option with all planning done for you.

Cool; glass holes it is. How many return holes would any of you kind people suggest? I was thinking two. Will I be ohk with just one or is two a good idia? Thanks guys.

Preferably dual overflows with dual holes making four in total and overflows at slightly different hights is how I roll

I have a lifereef hob overflow atm. its good quality, and has never failed, but it's intrusive inside the tank and out. And a pain when fish realize they can hide behind it when I'm trying to catch them. Next tank I own is going to have an external (hopefully coast to coast) overflow with a beananimal setup
