Gates GT14 Filter Mount - which filters?

I have 2 Gates GT14 video lights and would like to use filters for ambient light. Which filter should I use for blue water within a depth range of about 10-18 meters? What filters are you using? I would like something comparable to the Keldan filters. https://keldanlights.com/products/filters/filters-for-video-lights/1496-ambient-filter-af-12-b-72mm-4x-8x.html

I was looking at filters here: https://www.bhphotovideo.com/c/search?q=58 mm color filters

Thanks!

**If anyone is selling the filter mounts (2) and the filters, I maybe interested. located in USA.

Your best bet might be something like the Rosco 4360 cyan filter, DLWheeler. But hard to say without testing a keldan filter to figure out its exact transmission qualities...
