How do I increase light under water?

Hi all, I am currently working on an ancient tomb level which has a area where the player must swim underwater and place different items in different places, but I have so far been unable to make the area bright enough under water. To create the water I am using a post processing volume and the lake water blueprint from the water planes example and for lights I have a torch on the left and right wall which is using the emissive from a flame particle. The torches have no issues lighting the rest of the level and work quite well, but when it comes to underneath the water, barely any light manages to illuminate the area. I’ve tried several different searches on lighting water, but haven’t found any good solutions so far, that said I apologise if this has been asked before though.

Thanks in advance for your time.
