Best product for scale?

Well, I thought I was doing a good job keeping the water balanced and testing and all of that. Guess not! I will have to spend this slow workday refreshing and seeing if I have gotten lazy and forgotten something.
 
Hey there, bassett hound. Check your pH, CH and TA......pH being the biggest culprit.

If you problem persists, a dilute solution of muriatic acid (start with 3 (water) to 1) should clean off the existing scale.

As JasonLion indicates, proper chemistry balance is the key to keep it from ever starting.
 
In a tub TA levels control the PH. When TA is much above 40, the jets will drive the PH up rapidly. If your fill water has TA above 40 you need to lower TA each time you refill the tub. (40 is approximate, 30 to 60 depending on details, though often around 40).
