After 11 yrs of IG pool ownership, I have finally broken down and purchased a new tub. I have the 500 HotSprings Grandee http://www.hotspring.com/Spa_Showroo...l_grandee.html coming next week. I plan on running chlorine. My main question is whether I should purchase some diclor or just continue to use CYA/bleach?
Here are my numbers that I will fill from:
HotSprings recommends (in this order) balancing the TA to 80 ppm. Then, they recommend balancing the CH to 100 ppm. I am good here for now. Then, they target the pH for 7.4 to 7.6. I will use HCl unless there is a reason not to use this product. They do suggest using either NaHCO3 (to raise) or NaHSO4 (to lower) but I always have HCl on hands.
Finally, the manual says to add 3 teaspoons of diclor and bring the water to temp and run all of the jets. If the FC is at least 3 ppm then I am done. If there is less than 3 ppm FC, redose with 3 teaspoons of diclor until the FC holds above 3 and repeat as necessary.
The recommended levels are:
TA=40 to 120 ppm
pH=7.4 to 7.6
CYA is not mentioned. I will also add borates to 50 ppm as I enjoy the water conditioning benefits. Any other ideas?
