Last season I seem to have found the sweet spot in my pool chemistry where pH rise is no longer an issue with my SWCG, thanks to great info found on this forum.

It seems by keeping borates about 60 and TA about 80, pH will settle at about 7.6 or so and stay there all season. It has never risen above 7.8; this season hasn't gotten above 7.6.

I have a couple jugs of muriatic acid that hasn't been used all of last season and all of this season (it's stored outside in a covered plastic garbage can).

Is there a way to safely dispose of this old MA?

I thought I saw a post before about disposing of chemicals, but I can't find it.
