I'm using the TFP method for the pool, and as such, my pH tends to drift up, which I balance with muriatic acid.
For the next batch, I switched to dry acid, but read that it will make the water smell after a while, so I'll switch back to MA.
My problem is, when I add MA, I can often smell the chlorine, as much as I try to avoid breathing it in.
I have been researching this on google, but couldn't find out if the respirators I can buy at hardware stores filter out chlorine or not. I'm quite nervous with adding MA at this point because of the fumes.
