Sorry about that - yours is the first report I recall of an Intex pool bleaching -- doesn't mean it hasn't happened before, but I don't recall it. I was hoping that those pools had chlorine resistant dyes on the liners.

Yes, though: get a clean bucket or garbage paile, scoop out a few gallons of pool water, add the dichlor, and then pour it back in.

But, it's ALWAYS better to have the pump running during, and for at least an hour after, chemical additions.
