Draining and acid washing to get rid of black algae

[xoroniox]

Draining the pool is NOT reccomended however i had a serious forrest green water with bugs+creatures growing and swimming in my pool and before i knew any better,i used a fine mesh net to skim/net as much junk possible out of the pool after i drained my pool and did the acid wash on the walls/steps/floors then i refilled my pool and checked all my numbers and brought everything into acceptable ranges and shocked just for the hell out of i also have an inground pool diamondbrite finish 12,500gallon. Now after i did all that it took care of my algae/bug problem but the water was very cloudy for a couple weeks. i am NOT sure if it will work for black algae i never had that but i would not reccomend draining the pool terrible things can happen (crack pool deck, pool lifting out of the ground) thank god nothing happened in my case but i also didnt know any better and just drained it but i would not do it again. if i could do it all over i would just shock the hell out of it with tons of bleach and net it all out. i hope that helps a bit. good luck. -Arron

Thanks for your reply. I actually did a lot of research on black algae and determined our best course WAS to drain and acid wash the pool. We are not doing this ourselves, we have a professional doing it for us. The person I am dealing with is very helpful and has given me some excellent information. Thank you very much though, for your reply.
