If you mean algaecides, then NO don't add them OR the clarifiers. The clarifiers, at least, have their place in pool chemistry, but some work, some don't, and they all can complicate your pool problems if not used correctly. Your pool is cloudy because you're just now killing off a big algae bloom. Let you filter do it's job. Don't add any algaecides, either--the most efficient algaecide you can use is chlorine.

Don't make a very common mistake and try to rush things by throwing "goop" into the pool. Your pool didn't get into that shape overnight, so it's not going to clear overnight, either. Be patient!!
