My apologies if this isn't in the right place.
I have a bottle of "Phos X" left over from a closing kit I bought a few seasons ago (I no longer use the stuff after learning it was unecessary). I can't return it so it's just sitting in the closet.
How can I get rid of it? I guessing pouring it down the drain isn't a good idea. Can I add a little at a time directly into the skimmer (to avoid clouding the pool) over time until it's gone?
I don't know anyone I can give it to.
