My water is not black due to leaves or debris or algae - I have a cover and a leaf net - the black is due to combining leftover Baquacil with new chlorine.

I'm hoping several doses of shock will do it, but I'm unsure - I've heard that once you have Baquacil, you have to drain before switching over??? I don't want to shock like crazy, only to find out I still need to drain it out and start from scratch?

I tested at end of year, and algecide, etc, etc of Baquacil all tested as zero or not present - so I closed the pool in the fall using chlorine shock. But now water is black!!

Help!!!!
