    Such thing as "winter algaecide"?


    The pool closers I've used since moving in (2 yrs) use a winter algaecide called "On Guard" that I can't find for sale on the internet. It is a gallon liquid...I think the company puts in three gallons at fall closing, and instructions are to use one gallon again in Feb, Mar, April before opening.

    Is this stuff any different than other algaecide or algaecide concentrate that I can get at Leslie's or other stores?

    Any information regarding capability of the product is appreciated.

    Hi Jason

    Yes, it is! Thank you!

    Do you know if it is any different from other algaecide?

    Do you use it/are satisfied?

    I have never used it. I can't find anything that says which kind of algaecide they are using. There aren't any that I know of that are specifically for winter. I assume that is just marketing.

    it IS just marketing. There are only three kinds of algaecides--linear quats, polyquat, and copper sulfate. Since that comes in gallons my guess is it's a linear quat. The only algaecide that we really recommend is polyquat.
