Well the problem you're having with this FX is that Blitz doesn't ( yet ) support Cube environment mapping. It's been requested ( many, many times ) and I think it would be a very useful feature, but I don't see any practical way of emulating it.
I mean you're talking about placing a camera where the water is, rendering to that camera and multi-texturing the water with the view you just rendered. In essence. I think there's some stuff in the code archives about mirrors/reflections to give you a rough idea, but it's not really a replacement for cube environment mapping because you take a big speed hit. The wonderful thing about cube environment mapping is that it's lightning fast.
