Welcome to our forum.
Bill do you have a drain at the bottom of the spa? Never thought about using a bucket before. Sounds like good exercise. I'm assuming you used the bucket because it was faster?
I'm new to this and I'm having a CC problem. I never thought of a partial drain. Can this help my issue do you think?
Yes, I recommend Chas's law myself. I over did the chemicals when I was a spa virgin. I typically connect a garden hose to my HS drain at night after my soak and wake up to an empty spa ready for a re-fill in the morning.....
