Is it ok to add the dichlor through the skimmer/filter? I am afraid because the water temp is cold the stuff will not dissolve if I throw it in the water and I can not see the bottom to see if any accumulates. (I'm in PA and we have outside temps between 50 and 75 right now)
When should I test again for stabilizer? I have only needed to put 2 pounds of dichlor in today and I was wondering how much it takes to raise the stabilizer.
When do I add the Polyquat?

Thank you for you time and patience!
