I'm having my drain repaired so the pool will be empty tomorrow. I have been fighting several small black algae spots. Since the pool will be empty is there anything I can put on these small spots to kill the black algae. I am trying to avoid going out to buy anything due to our national quarenteen. I have vinegar, shock chlorine packets, algaeside and chlorine tablets. I also have soft scrub. Can I do anything with these? If not, if I can go out what can I purchase for an empty pool? I already have wire brush and have been working on them. Thanks.
