Generally mixing chlorine types is a VERY bad idea. In enclosed spaces it can cause an explosion. Despite that I did add Cal-hypo via the skimmer once, and I currently pour my bleach in there. But if you've been doing it for a long time, it might be better to pour it into the return stream instead, at least for this season until it all washes out.Originally Posted by mspool
But that's my guess. You can ALWAYS add bleach to the return stream.
