    Last years leftover 12.5%??

    I have about 3-5 gallons of 12.5 % left in my 15 gal drum, its been out of the sunlight and capped off in the drum in my pump house, will it harm anything by manually dumping it in initially this year when I open just to use it up before I refill with fresh? Or should I just dump it out? I realize its strength will be diluted but I would imagine it should raise my FC a little bit?? Rather then just wasting it??

    You should be fine to use it, it will likely just be a little weaker.

    I have 12 gal of 10% from last year and it doesn't seem to be any noticeably weaker.
