Muriatic acid versus liquid shock

Postby haskins200 » Mon 15 Jul, 2013 20:49

I am torn between using either muriatic acid or just putting liquid shock in my pool. I have an above ground 24 ft. round pool with a cartridge filter pump. I can't manage both the ph and alkalinity. It is so cloudy you can't see 2 ft. in front of you. I was told to shock it with liquid shock, but then I was told to add this other type of acid? Both the ph and alk is high! I have shocked my pool twice since spring.

So should I just shock it or add the acid? And, I was told by pool experts than you can enter your pool 1 hour after liquid shocking it? True or false?

Thanks for any input.

Muriatic acid versus liquid shock

Muriatic acid and liquid shock are two different things
Muriatic acid (hydrochloric acid) will lower TA and PH wheras liquid shock would be chlorine (sodium hypochlorite)

It has been well documented in this forum to reduce both TA and PH then increase the PH with aeration
You follow the procedure in viewtopic.php?f=16&t=390

I wouldn't use the pool untill you have taken readings and found them suitable
