block fill prep

Thanks!! We decided to leave the vinigar in over the weekend. It definatly made the scale softer in just a matter of an hour. Monday will clean it out and run it thru a hot tank agian if needed. Then block fill. A buddy who did his last year said to let it set a week or 2 before machine like was suggested. If its not clean to my satisfaction, will get the muratic acid. Thanks!!
