Cyanuric acid is generally called chlorine stabilizer and it is used to prevent the suns UV rays from eating up the chlorine in outdoor pools. Because most spa's are covered when not in use this is generally not a concern for spa or hot tub owners.
If you do however have an outdoor uncovered spa and you wish to raise the CYA level you would simply visit your local pool supply store and purchase some chlorine stabilizer, just ask for cyanuric acid and they will know what to get you.
I have the same problem with my 2000 gal. in-ground spa. Each week I have to add muriatic acid to reduce the PH. Since my spa is small, in relation to a pool, I usually only have to add about 1/4 - 1/2 cup of acid to bring the PH down to the perfect range.

In the game "Sara's Super Spa" (the original one) there are exactly 20 levels. You will know that the game is over because Sara will say that those four weeks were the toughest of her life, and her friend will also say that with great popularity comes great responsibility. Sara will also mention that she needs a break. Good luck with the game!

The blue/green stain is copper from your heater. Your pH and alkalinity are too low. You have to call someone (with experience) to drain and do a light acid wash to remove. Test water more frequently and adjust as needed to avoid same situation. Your spa will only handle a few acid washes before you have to re plaster. Your heater will not tolerate low or high pH.
