I had a bottle of pH minus from last season that I've been using to bring my pH down, and planned to switch to muriatic acid when it's finished.
When I was in Canadian Tire this past weekend, I decided to get myself some Muriatic acid. I get to the paint section and I see this plastic bottle of muriatic acid that is wrapped in a plastic bag that is sealed, with all kind of warnings about wearing goggles and long gloves, and always keeping the bottle upright and making sure the cap is well sealed.
I'm like whoa whoa whoa whoa... this doesn't seem inviting at all. My pH minus bottle has an orange cap and looks cute.
1- Jokes aside, what's the downside of using pH minus vs muriatic acid? I know TFP recommends muriatic acid.
2- And if i do get muriatic acid, any pointers about using it safely and how to store it?
The fact that the bottle itself was sealed in a plastic bag made me think that I wouldn't want to keep any left over muriatic acid in the garage all winter, have the fumes evaporate and do god knows what.
Thanks in advance
