Souns like black algae, and unfortunately, once you have ie, it's really tough to get rid of. What type of finish does your pool have? Did you have any success with the treatment you used?

One of the larger spots is virtually gone. I just notice a mustard color spot in the deep-end. I am still scrubbing the smaller black spots with the metal brush but it does not seem to be making any difference. I treated the pool with the algae killer Friday. Can I treat it again? Should I clean the filters also? The pool is made from gunite and I'm not sure what the plaster/paste that they finished the pool with is. Thank you for your response.
Post a complete set of water testing results taken with a drops-based kit. Make sure that your CYA level is one of the things you report. What is the ingredient in the 'shock' you are using?
