Anyone local have a lifereef overflow

Proper set up is key with these.
If your flow isn't strong enough, you will get bubbles building up in the u-tube that will eventually break siphon.

The lifereef u-tubes have a gradual curve that makes this a lot less likely but as long as you have a strong enough pump, you should never, ever lose siphon with one of these.

I hate to say it, but your friend just didn't set it up properly.

I had a couple of issues before I figured this out and not one siphon break in close to 4 years now since.

Speaking as a past lifereef and aqueon overflow user.

Now, I just build my own out of acrylic and pvc.
