Can’t see through water in aquatic quest mal

i have watch a couple of other people play the aquatic quest map on YouTube and when they get to the part where you have to swim through the closed caves they can see about 10-15 blocks ahead of them. When I play it I can see about 1-3 blocks ahead of me. It’s impossible to even try and get through this area of the map because you can’t see where you are heading.
