Solar Cover Colours
I'm confused about all the solar-cover-colour choices available.
Every website seems to say something different about what the types of covers, will actually achieve.
(ie: some say "black" is good for heat retention, others say it's bad because only the cover gets hot and not much tansferance to the water, especially since it blocks out U.V.)
I was unable to find an independent study of the various types of solar blankets.
clear vs light blue vs dark blue vs blue with silver backing vs blue with black backing vs all black
and then there is diamond shape vs round bubbles
and how about how thick the blanket is .. the different MMs...
is there really that much difference in performance?
Plus I read about shrinkage. about how it's a good idea to get a few inches overlap all the way around because the blanket will shrink. ( one source even said, if you cut it again, it will shrink past the new cut ? )
Does the measurements listed for sizes sold include that overlap?
( ie: a 40ft pool length buys a 40ft blanket, then it shrinks & is now not touching the sides anymore?)
