shelf life of mixed 2-part

kinerson · 12/24/2007, 04:16 PM

I was wondering how long the mixed calcium solution and how long the mixed alk solution can keep. Does the baked baking soda loose it's high ph in time after it's in solution? I would rather mix up 6 months of both items twice a year then mix it up every month.
Thanks,
Greg

It should be fine indefinitely if it's kept covered and not allowed to get too cold. If it gets cold, it might need to be reheated to redissolve any precipitation.

I keep it in the basement next to my sump. The temp ranges between 65'f in the winter to 75'f in the summer so I guess I should be fine.

Thanks for the info Bertoni
