Just finished putting in five gallons of white vinegar and will give it about 36 hours to work. Judging how long it took the scale to dissolve in the cup, this should be long enough with that amount. I plan on doing a couple of quick on/off shots of water to help stir things up a bit tomorrow so that is another reason why I used that much. You can see the method I used to get it in there. Its a two cup container with a makeshift spout made out of masking tape. Worked well in the confined space. There were bubbles forming in test cup and I can hear the tank bubbling. I left the emergency pressure valve open on top as well as the bathroom hot water tap so there is no pressure build-up. We'll see what happens.
