I opened my pool 2 weeks ago and it is green! Yuck!. I have tried all I can. The reason I do not convert to chlorine is because my husband hates chlorine smell. Has anyone tried using Simple Blue?? Right now I am letting my pool run out of Baquacil and then I am going to switch it over. Please let me know. My pool is an above ground and is 18 X 24. Thanks for any info as I am very frustrated right now.
