Liquid Solar Cover may be a good choice in commercial applications where a hard cover is not allowed or in a residential setting when the customer would prefer not to wrestle with a hard cover any longer.  Using liquid solar cover is very easy just add a few ounces once or twice a day of liquid solar cover to your pool that's it.  There is also a optional feeder pump to add liquid solar cover automatically.
