Pool cover to keep water less warm

[pj123]

I find our pool is too warm to swim in the evening. Would a pool cover help? Found this product but they only promise a 10% reduction in water temp.

I suppose it might work but a 10% reduction doesn't seem much. 

 

I'd think any bubble type cover with a reflective surface would work.  Preferably a silver surface (like a mirror). 

 

There are possibly other options but then the cost will go up accordingly.

I think you're going to need a roof over it, and no sun exposure, if possible..  Ours (Udon Thani) had a roof over it, and didn't get any sun in 'hot' season, and was nice & refreshing most of the year, except couple months in cool season.  Way too cold to swim be in.   It was also 2+ meters deep when full (one half) and 1M deep, the other half.

I know a few who are using large blocks of ice. Cheap enough.
