Yeah there is at least 2 missing posts from me. One if which describes what the cya I got contains. Label says cya and sodium bicarbonate but has no percentages. Is that OK?

Other part of that post was about shock at the pool store. 12.5% sodium hypochlorite gallons for 2.99. Which is the dame price I get 6% bleach for. Any reason to just not buy the liquid shock? Is it goop? Doesn't list any other active ingredients.
