long term adding muriatic acid?

[mikergibson]

I understand that this is some nasty stuff, I have started using it instead of the dry acid based on folks on this forums recommendations to reduce my ph every 3-4 days.
Are there any known problems with long term use?

No. It is hydrochloric acid, so it only adds hydrogen and chlorine to your water, so no accumulation of undesirable chemicals.

The potential problems are more associated with storage & application outside the pool. A leaky bottle or some splashed on your skin isn't fun...it's very strong acid. I am always amazed when I take the lid off and it starts "smoking" from the moisture in the air.
