Take a look at Beananimals solution:

Have fun!

Sorry about this it's just something that I feel needs to be done... I hate having to click on pictures to see them... I'll be following your set-up too

[paddyob]

Can someone teach me to post pics properly....haha. I only know how to make the little attachment links. If you dont wanna click.... let me know how to attach full pic!

Thanks

where ever the image can be viewed you can right click it and click "Copy Image Location" then you can paste the link after clicking the "Insert Image" button of the post location (the one with the mountains and the sun or moon on it)

Chambers changed.... 8"-12"-12"-8". want to ensure enough space for skimmer... after baffles are in chambers wont be same size as need to allow for space between them.

Depth of each also changed.... 13"-12"-10"-10". He is going to build a 2" riser for the skimmer to elevate it a little so the depth will be at 10" max.

Your friend is right. A single overflow is a disaster waiting to happen. It woudn't even be necessary for the hole to plug up. All it would take is for the return pump to decide to pump a little extra water and the tank would slowly fill to the point of overflowing.

The good news is - all is not lost.

You're tank has 3 holes drilled in it, not just one. If you bring the return lines up over the tank rim, you can use these holes as part of your overflow system. There is no reason why the return lines have to come in through the back of the tank.

Plesae do read about the 'beananimal' overflow. You're tank has everything you need for this and it is such a great overflow system. I used it on my first tank and will use it on my new tank as well.

Basically, all you would need is a single piece of acrylic bent into a L shape to create an internal coast to coast overflow. Have the piece custom made and use a minimum thickness of 1/4" to avoid bending under the water presurre inside the tank. You can use silicone to hold it in place. Silicone doesn't hold acrylic to glass very well, but for this purpose it works fine.

I can show you some pictures of how I did exactly what you need to do if you would like?

The only disadvantage of this approach is that you do lose some realistate inside the tank.

THATS A GOOD IDEA!! I will be building my tank in so nobody would ever see the plumbing behind.... I will make it into a triple overflow and use pipe for returns (I assume) and bring them over the top in a hook-like manner.

If you have pics I would appreciate it!!

coast to coast overflows are way more efficient than a smaller overflow box in terms of surface skimming.

[Slick Fork]

Absolutely more efficient but they do rule out the use of a wavebox in the future so keep that in mind.
