Black light, Lava rocks, Running the filter, Getting a algae fish
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
Test for ortho phosphates
Convicts are very aggressive fish. You should just consider using something else to get rid of the algae. I'd suggest something like Aquarium Pharmaceuticals Algaefix which works wonders and has a good price.

Algae is grown by ammonia in the water that is turned into nitrite/nitrate is food for algae to grow. It also needs a little light. To get rid of it you can put fast growing live plants in your aquarium to reduce the nitrite/nitrate in the water that algae feeds on. See Related links below
If its a plastic bowl get rid of it and buy a metal dish or a cermic one. Make sure you keep the water dishes out of direct sun light. That might help the algae grow, and wash them regularly to keep bacteria away.
