I suspect I could fill and drain it forever and not get all this stuff out. What I need is access to the inside - ideally, from the side as there's not much overhead clearance.
Any Aluminum water tank on any boat is a disaster. Aluninum reacts with chloride which is in most Municipal water systems. The crap you see coming out is aluminum chloride which is the choline eating the aluminum.
