[EDIT]Is there a way to delete roblox water?

I've made a terrain which would work for what im doing, With water... I've realised I can make something thats more efficient and uses a block instead of the water...

Is there a way I can remove it? I would re-generate the terrain but I cant remember what I had the values at and the settings it is at the moment would work great.

If anyone could give me an idea on how to remove roblox terrain water (Without clicking on every single block with the remove tool) that would be great =)

EDIT: Or is there a way to find the figures I put into the terrain generator in the first place so i can just regenerate the terrain with water set to 0?

Thanks for reading...
