Water material going completely transparent at moderate to long distances

Hello!

I ran into an interesting issue today when creating a water texture from this tutorial. At short distances the water looks good and has depth fade but at longer distances it seems to go entirely transparent. Here is a video showing what it looks like but I suspect some of you know what it is before even looking. I tried to tweak settings in the material for quite some time but was unable to figure it out. What might be causing this?

Thanks!
