You just have some stubborn algae and you killed it in the bucket (and in your pool since you have CCs). Keep shocking, it will work eventually.
linen said:I agree with the frog, nothing in bleach should cause white cloudiness other than that fact that it is murdering Algae (well said frog!). The bucket showed us something else, it seems unlikely that you have high metal content in your water, since the water did not "tint". That is a good sign, though maybe not the final word on metals.
