Is there a patch for above ground pools that are full? The hole is very small down towards the bottom.

I am in the process of switching the chemicals in my swimming pool from bacquicile to chlorine. I have treated the pool to rid the bacquicile as was instructed from the pool store. My swimming pool which was as clear as glass before is now a mirky yellow since I put in the shock treatment. Please tell me this will clear up fast. Suppose to have company over tomorrow to swim. Thank you
