If you had some CYA last year and you have none now, it may have broken down into Ammonia. That takes huge amounts of bleach to neutralize, and it will use the bleach about as fast as you can pour it in.Sorry its not a new pool. Short bought house couple years ago pool in bad shape. Finally coming around thanks to just browsing this site that's when I became a supporter. Did I say awesome site! Now back to pool. Opening this season this is where I'm confused do I bring CYA up before slamming to open? Or both at same time. Pool is pretty green had a very warm winter. Thank you sorry for confusion!
