Ok all you hot tub heros, I'm a first time hot tub owner and we've had our 2013 Hot Springs Vanguard since sept. 18, 2014. When they came out and set it up, hooked up the Ace system, balanced our water, and we have been fighting our free chlorine ever since. Several weeks into it they recommended that we have the ozonator disconnected, which we did. They just disconnected (not plugged off) the line and we are still having trouble with the free chlorine. We are using the tub twice a day 7 days a week for 20 mins in the evening and 15 mins in the morning. All other chems are within range, ozonator is disconnected, water hardness is good, ect.... Could my problem possibly be the Ace system itself just simply not producing chlorine? I have the output level set at 7 right now, but to no avail. I have to put 2 teaspoons of shock in it every morning, and this is raising my CYA levels too much, Is this normal?
