Adding a Frag Tank - Question

[NEWSALT]

I've decided to add a frag tank to my system. My question is, is it ok to tee the overflow pipe from the frag tank into the overflow pipe from my display tank so I can only have one pipe emptying into my sump. Any disadvantage to doing this?

Thanks

The frag tank would require it's own overflow, of course. However as long as the plumbing to the sump is large enough, you should not have a problem using a T. Usually I figure a 1" pipe used on an over flow is good for about 600 gph. 1 1/4" pipe is good for about double that flow.

If you find you do need larger pipe, you might be able to drill a larger hole in the sump, at the same location as the existing one, and then plumb a T right after the larger bulkhead fitting you would need to install.
