Does a solar cover help so much to prevent Chlorine from evaporating....alot?
I checked my CL level 2 days ago and it was at around 9.5ppm. We have strong sun and cool nights here lately and it warranted me putting my solar cover on. Well I checked the CL level today, 2 days later, and it tested at 8.5ppm so in 2 days of full sun with the solar cover on I only lost 1ppm of CL.
Does this sound right to you guys?
I do have my liquidator shut off too so no new CL added there.
