Ok… So, this is my first forum attempt. Im not exactly sure if Im doing this properly but here goes.
I currently have a 20,000gal. spa that i am maintaining. Chlorine at approximately 3.0-3.5, Alkalinity at approximately 160ppm and PH at approximately 7.3, and the temperature at about 94 degrees thats just the basics. We have a CO tank to automatically keep the PH stabilized, and a chlorinator to keep the Chlorine automatically stabilized all by computerized system that is manually set to desired levels of each chemical.
Now, I now I need to lower the TA to approximately 80-100, and Im completely aware of how. But, I have 2 questions that I may need answers to.
1. What causes the PH to increase drastically causing the CO tank to deplete more than usual? And how do I correct it.
2. Our calcium Hardness is always really high. How do we prevent it from increasing so much when using calcium hypo-chloride tablets, and without constantly draining the pool water? Is there a tablet that doesn't have calcium in it???
