How do I see my alpha / opacity on my fluid render in Houdini?

Is it possible to see it in the Render View window?

The alpha for my last fluid was completely solid and I was expecting a completely different result that was more of a gradient on the alpha.

I was using the tinted glass material for my material.. not sure how to get the results I'm looking for.

Please help.

Glass/water materials will render opaque/solid alpha, as the refracted ray transmits the color from behind/through the object. Alpha transparency is used for sprite/particle effects or for other non-physical effects.
