JustBlue is effective in making spa water maintenance easier by reducing surface mineral build-up and therefore making it difficult for biofilm to develop.
Just Blue has a pH level around 6.8 (as compared to pH levels around or above 10 with most of the other alternatives). Due to its low pH level.
JustBlue helps reduce pH creep on Spaboy and Onzen systems rather than amplify it.
The box comes with two bottles which is a 20 week supply for a 7 foot spa with no salt system and a 20 month supply with a salt system.
