I finally figured out what I believe has been causing the problem with my water tank - it's not the tank or hoses - but it's been the water I've been using.....
Turns out the marina water supply, while originating with the local water utility, sits around in hundreds of feet of water pipe sitting along the docks and slips, heated by the sun and growing all kinds of gunk inside the pipes!
Recently, we had 3-4 days of bad weather, and nobody was around the marina using the water. When I opened the tap to fill a bucket, I found a lot of green and brown gunk gushing out of the hose.
I checked my water tank, which I had mostly drained, and I found the exact same gunk in it.
I cleaned out the tank and rinsed the hoses with bleach & vinegar.... and physically removed all signs of gunk.
I refilled the tank with water from my home (which is pretty good) in a five gallon camping jug, and now the water is clear, doesn't smell bad and can be used for washing up.
I will check on it over the next few weeks to see whether the Marina water has been the problem all along.

I fill the tank with my hose at the marina also but I also add a few ounces of bleach with every fill up. I will say that the tank and hoses are clean without a foul smell.( Sara has a very good nose ) I probably have about 30 boats between me and the start of the hose run so someone is usually using the water.
If the marina is selling (included in the cost of your slip) potable water, it should have a minimum chlorine content at each of the taps when tested. If it's growing crap in the pipes, the chlorine isn't there. They shouldn't be reporting(selling) it as potable. The local health department might have an interest here. They certainly will if somebody gets sick.
It should be clearly marked as NON-POTABLE WATER, NOT FOR HUMAN CONSUMPTION. Because chlorine leaches out or dissipates in standing water, the solution might be as simple as letting the most distant tap run all the time thereby preventing the standing water issue you described. Not very "green", I'll admit but it sure beats water-borne illness.
