I have not used my hot tub for a few seasons. I just finished cleaning and filling it up with 350 gallons of water. I also have a fiberglass pool and I use the sock method to add cya. I plan on using chlorine as my sanitizer. How should I add the cya....just dump it in or like my pool put it in a sock? If I use the sock method,how long do I have to wait to use the hot tub.
I also purchased a swg for the hot tub....any tips for them? I would appreciate it.
