Which is a better solar cover for a swimming pool.Blue,clear or black?

Question

Do they even work or are they a waste of money?

Answer 1

They work evenly but get a black one...Because if you want the pool water to be somewhat water black absorbs heat better...And with have the water a bit warmer than clear..Or blue.

Answer 2

None of the above!!!!!!!!!!!!

Forget the old ideas.  Use the Ecosaver fish or whatever the brand is in your pool catalog or local pool store.  Basically it is a stabilized isoprobol alcohol.  When the sun hits it it magnifies it's rays and heats your pool/  The nice added benefit is that it also aids in preventing evaporation.  I have really done some experimenting with them through the years being very scheptical at first and now after sicking an ex Dupont engineer on it (retired) I am a true convert.  Forget the bubble wrap and go with the new deal.  The covers I still sell to the same old people year after year.  Actually about every two years.  Of course those peopel are usually over 50 and will not change or accept it.
