If you have a severe black algae problem that you have been mitigating for years and can't get rid of can getting a very dark blue liner help to hide the black algae stains?

In a word ~ NO. If the algae bloom is that severe maybe a replaster is in order. Sounds like you need to be more diligent on chemistry in the pool along with proper filtration among other things. Sounds like a problem of neglect. Black algae will bore into the plaster unlike green algae. It is very difficult to get rid of especially on rough plaster. You cannot cover over it or paint over it. Oh, the dark blue liner or any liner can and will cover and hide the algae problem but you will still have the algae problem and in fact compound the problem. The algae could bore through the new liner and then where will you be - - right back in the same boat. k

What causes black algae?

There is no such thing as actual black algae. It is just a name given to crystallized green algae. Green algae that can not flourish will die and crystallize and try to grow again and again in the same spot forming those black buds. Usually you will get black algae from keeping a constant level of chlorine say 3 to 5 ppm's and not shocking (Raising the chlorine level over 10 ppm's) the pool often enough.
