    Alternatives to polyquat?

    Hello all, I'm in day 2 of my slam before closing and I pick this up at the pool supply store did not see polyquat. Will this be ok or should I try to find polyquat? Also do I need to let my FC drop before adding algaecide? Thanks in advance!!

    We recommend polyquat 60 because it seems to be the most effective. Others may work, just not as well.

    Thanks, should I let FC drop before adding it? I've heard that high chlorine levels could effect algaecide in some way?

    Re: Alternatives to polyquat?

    You should return it. It has very little algaecide.

    hth Aglae Guard MSDS say it has 5 to 15 % of the active ingredient: Alkyl (C12-C18) dimethyl benzyl ammonium chloride 068391-01-5

    A recommended algaecide (60%) has 60% of the active ingredient:

    I would wait until you FC is halfway between shock and normal. The key to opening to a clear pool is to close when the water temperature is below 60.

    You can get a recommended one via Amazon:

    I always use Amazon. It is difficult to locate and always twice the price of Amazon.

    Re: Alternatives to polyquat?

    Algaecide 50 is a linear quat so while it works as an algaecide, it can also cause foaming and it also breaks down more quickly from chlorine so has noticeably higher chlorine demand. Up to you whether you want to use it -- you could try it and if you don't like it then can discard it. I presume you are only talking about using it for closing the pool, correct? Algaecide is not needed when you are maintaining the pool at the proper chlorine level relative to the cyanuric acid level (i.e. following Pool School recommendations).
