    Stir my chlorine tank?

    I have peristaltic pump and 15 gal tank for liquid chlorine. I keep the tank at 8.25% concentration because that's how I usually buy bleach. From time to time I pickup 10% at Home Depot, in which case I add 27oz of water per gallon to get it back to 8.25%. I always assumed it would mix by diffusion, but then I saw the Liquidator floats a layer of water over the bleach. I don't understand how that works, but then the question is do I need to stir my tank after adding 10% and water?

    The bleach is heavier than water... when you add bleach to the pool it's best to add it pencil thick over the return because it is heavier. Hope this explains why water would *float* on top. I'm sure if I'm incorrect, I'll be corrected. Lets see how I did...

    It does make sense that water will float on bleach, but it seems like eventually diffusion would mix them. Anyway my pool chemistry is stable so I'll just assume stirring isn't necessary.

    Funny, I was about to post the same question...I thought water would MIX with the bleach, but now I am concerned that it won't.

    Water and bleach will normally mix together, but it is possible to keep them from mixing for fairly long periods of time if you are careful. Still, it doesn't take much to get them to mix throughly, and once mixed they stay mixed. The Liquidator has a special setup to prevent turbulence at the boundary between bleach and water. Without that it is fairly difficult to keep them from mixing.

    Cool so it sounds like us adding water to equalize the concentration will work thank you
