I got a nice wiff of MA fumes tonight, adding some to knock down the PH. I'm fine, but wow, that stuff is strong. Next time, mask. I had gloves and glasses on already. Anyway, I read up on the concerns of the fumes (I'll live another day I guess) here on TFP, but read one more thing that made me wonder if I'm ok doing what I'm doing.
It says that MA is corrosive to metals, especially stainless steel. I add the MA in front of the return jet in the deep end, which is about 24" to the left of the deep end ladder. Do I have to be concerned about the heavier concentration in the vicinity of the ladder damaging it over time? I assume once the MA hits the pool, in the water stream from the jet, it's neutralized pretty quick. I'm thinking the comments on being corrosive where if it was undiluted and directly applied to metal. Thoughts?
Lastly, I read a lot about storage. Some folks store it outside in plastic bins. Isn't that worse than say indoors, as the temps can get quite high outside? I have it on a shelf in the basement, but reading about "vented" caps made me wonder if this is a bonehead idea. The threads I read were a few years old, so I'm wondering what the latest ideas may be.
