Acid Water

I am trying to create the water found in the Canals level that is
yellow, radioactive, and hurts the player. I tried a search and
came up with no answer, so I apologize if this has already been
discussed. Also, this might be simple and I might just not have figured
it out. I am a new mapper, and trying to learn as best as I can. I
searched through the various water textures in hammer, but was
unsuccessful. Any help would be greatly appreciated.

The texture is: nature/toxicslime002 (remember only the top part of the water has this texture on it, the rest has nodraw)

To dammage the player: place a trigger_hurt over/in the water, and set the dammage type to RADIATION or CHEMICAL

Also in the trigger_hurt flag check "only clients not in vehicles", otherwise if youre in the airboat on the water it might hurt you.
