First post, hello everybody!
I use my hot tub once per month max. Maintaining it (ph, sanitizer, etc) is a bit of a hassle and time consuming. Rather than always keeping water in it, I was thinking about filling/draining each use. So using it similar to a bath tub.
I would use the drain water to irrigate my lawn.
My question is...if draining/filling each use, do I still need to adjust pH, sanitizer, chlorine ppm, etc each use, or can i treat it like a bath tub where those issues aren't important.
Not concerned with cost of drain/fill or heating new water.
Thanks!
