How to I build an overflow in a tank?
 

Okay I have read a bit of info before starting my tank. It looks like I will be buying used equipment with a sump. From what I have been reading it looks like a hang on cpr overflow is not a reliable as a built in one. And I am totally scared of having a flood if the siphon breaks. So the questions is do I just buy some arcylic to build my own overhang and silicone it in the used display tank I bought??? Then get someone to drill the holes in the used display tank to connect it to the sump. Can some one provide me a DIY link to help me out.

Thanks

well, I dont have a DIY link for the corner overflow, but it should be pretty simple. Just two pieces of acrylic that are the same height as your tank. I'd make one piece about 5-6 inches wide and one piece about 3-4 inches wides.

Silicone it to the tank, dremel out some strainer holes and get it drilled...

Maybe someone else has better info for you tho.

Or you could just put a bulkhead in the bottom of the tank and run a pipe up the the desired water level and BOOM you got a drain to your sump with no overflow box needed. :biggrin:

Other than some people finding this unattractive, why don't more people do this?

I was just reading the previous post, and thinking the exact same?

Wait a minute I did that with my 90. Just covered the corners in black acrylic.

Beacause they find it unattractive. :razz:

Well Yes it's un attractive but it's simple :biggrin:

I have this type of set up in my 75 g refugium and my 50g frag tank.
If I had to do this in a display tank I would just use black abs for the standpipe and soon one would not even be able so see the pipe.

Wouldn't a box do a better job of skimming the surface, than a stand pipe by itself, or is this not a big enough improvement to make it worth it?

Not going to make a huge diffrence as it's doing the same thing.
