To help removing scale before draining your spa, try ScaleTec Plus. You should double check that it is okay for plastic/fiberglass shells. It is from McGrayel Corporation, Easy Care Products Division, which is located in Fresno, CA, USA. Their website is www(dot)mcgrayel(dot)com; however, it has had problems every time Iíve checked. I have found this product at a few local pool supply retailers and just today my local Leslieís. Reportedly it is real good at removing scale with natural chemicals, which are less likely to create other water chemistry problems. Please reply to your post with your solution (especially if you used this product and like/dislike it).
