Updated to 1.14.x
With the recent ocean update I recommend you actually tweak the value of fog to a value that is a little bit over 0 instead. That way it would still look like you're under water.
I liked how it looked at 0.0075 for water fog.
edit: I made a mistake in the config text. Vanilla's default value for water is 0.05, not 0.1
