Give it some time. I know you are anxious, but sometimes the best thing you can do is to have what we call P.O.P. -- pool owner patience. Keep at it. Keep your pump running. I would not suggest adding a clarifier at this time. Sometimes getting in too big of a hurry to add extra stuff just causes extra problems. Especially since your water is cold and you won't be swimming for awhile anyways. It'll clear.
