Yes, some time difference, I heard on the UK news that a total water ban in California was it? I understand the issue, with non box/oval pools can you cut the normal cover in two to make it easier to manage? Rather do that than add the liquid cover.
No info I am afraid, expected some from a case in the UK but the gagging order prevented it. Just to extreme for me, I want water as pure and clean as I can get and a pool cover is vital during summer, it seriously reduces chemical and water usage but I know the conditions in parts of the USA are extreme to some of our weather.
