For those of you with variable speed pumps and this style of chlorine feeder, how do you get the puck to dissolve? I do use liquid chlorine for most of my chlorine needs but when I'm out of town I rely on this to keep chlorine levels up till I get back. I have the valve on the black tube fully open and the single puck I put in at the first of April is only about 3/4 dissolved. When I had a single speed pump the pucks might last 2 week tops.
