The primary fact in which scale starts to build up is due to calcium hardness in your water, this due to your water balancing going out of balance.  It really is imperative when looking after your tub that you start with keeping a keen eye on your pH levels and your Total Alkalinity levels which are the framework to managing water effectively. 

When your water pH goes out of balance you will find that scale/calcium will start forming on your hot tub surfaces, seat wells, and in your pipework and jets.
