chlorine and solar covers

Will keeping my solar cover on help preserve the chlorine in the water? just curious.

It should slow down chlorine loss some but not totally.

Good to see you back again this year.

Thanks! The conversion to chlorine from $oft $wim was the best thing I did. WAY cheaper, and BBB has been super easy to maintain so far. This forum taught me everything.

Would a blue or semi opaque cover slow chlorine loss more than a clear one?

Yes, the more opaque the cover (especially to UV), the lower chlorine loss from sunlight. The downside is that you'll also get less heating of the water from sunlight so may not get the pool water temperature to be much hotter than the average day/night temperature if it's too opaque. If it's more opaque, then a darker cover plus water circulation can still heat the pool somewhat, but a mostly clear bubble-type cover heats the best (though doesn't protect chlorine loss very much).
