The OP is concerned about his print wash water, not his used fixer.When you think of dumping darkroom waste water, chemicals at sea, no a marina or in a slow river or lake, take a moment to consider how many parts per, what, trillions (?) of gallons of water, osmosis into the Gulf will be the result of doing so.
Cruse the Pacific side or out into the Atlantic, you could maybe pick-up more of natures chemistry in a gallon of sea water, whatever the result, thinking about the math is fun, and I'm no math wiz, to be certain.
It's in coastal waters that you'll no want to dump in, and you can cut down on silver release by first pouring used fixer into a squeaky clean plastic bucket (first use) with some steel wool, and replace the silver with iron/rust in the hypo, while the silver plates out to the inside wall of the bucket.
After a few day, THEN, dump the rusty water into the open sea, with deforming the bucket sides, so the plated out silver on the inside does no come loose and go into the sea as well.
After this, just continue to remove the silver from fixer, letting it build up the plate inside the bucket, until it's thick enough to break lose when the dried inside wall is pushed inward, so you can recover the minuscule amount of silver and keep in in a small, lidded jar.
IMO.
But again, not with RC prints.Permawash is a good way to dramatically cut down on wash times and water usage.
What is the point of piping the water onto the print and then back into the drum? You might as well just put the print into the drum.
Use Hypo Clearing Agent. The rocking of the boat will help the development agitation.
I'm curious - how do you plan to dispose of that 55g of water? You may want to have 2 wash containers. When so many prints have been washed, discard the water in the first container, then the 2nd container becomes the first. Fresh water is added to the container you emptied.
Y'all are fixated on sea water. I live on a boat, my storage unit does not. It is a normal, land based facility that is absent of pontoons. I do not have to swim a moat of salty sea water to get to it. I do not use sea water for anything in my life, except to keep my home afloat. I will never use, nor even consider the possibility of using, sea water for anything. I know what lives in it, and I've seen what floats around in it.
I suspect some folks are thinking the pristine water surrounding a Pacific atoll rather than the water the bays around Houston. And I'm not sure the the water around those Pacific atolls is that pristine anymore.

You can calculate this yourself as you need about 1 water exchange per minute in whatever you wash in;Also film and RC-papersneed to was for ten minutes while FBpaper neds to wash between 30-60 minutes.I live on a boat and try as I might, I have absolutely no room to set up a dark room. I do however have a large storage unit with electricity.
If I took a 55g drum of water and plumbed it to a circulating pump, how long could I theoretically use it to wash prints before it became ineffective? Emptying it and refilling it once a week is one thing, but once every 6 hours is another.
