    Cover Free

    Hi there,

    Do liquid covers like Cover Free (Natural Chemistry) really work?

    Welcome to TFP!

    Yes, but only just a little tiny bit, especially if there isn't any wind. They are nowhere near as good as an actual solar cover. For most people they aren't worth the expense.

    Thanks a lot!

    It usually gets windy in the afternoon here. Enough for the chlorine floater to be on one side constantly.

    The guy at the pool store claimed that all solar covers, liquid or non liquid have the same results when being tested and just different price advantages/convenience levels.

    Didn't mention the wind at all...argh!

    Btw, the reason why having a cover came up was because I have been dumping lots of chlorine into my pool and couldn't get a reading. I brought my water to the store and they found out that calcium is at 900. Supposedly, our fill water out here is around 200. He mentioned that a pool cover would help the evaporation and therefore keep my calcium lower over the year.

    Any thoughts on this?
