    Just wondering if you can leave mixed chemical in your tank for any length of time. I am flushing my tank after every usage, but I'm wondering if it would be ok to leave it overnight if I had to? I use Momentum. (last years stuff).

    Just momentum? Any sticker or surfacant? Best bet is to do a jar test with the appropriate ratios and see what happens in 12 hours.

    Leaving it overnight should be OK. Just make sure it is thoroughly agitated before using it the next day.

    Is your tank fiberglass or poly? If poly your chemical will degrade
    quicker, but regardless don't be concerned with anything less than 48 hours for most products. We usually mix at mid label rates, i.e. if the label says 1.2-1.5, we mix at 1.35, allowing for a 10% buffer either way. All of my tanks are fiberglass, and we regularly mix Friday afternoon for our Monday work with no problems.

    I use spreader sticker, and my tank is poly. I guess I'm cool with leaving it overnight. That was my main concern. Thanks for tips guys. Learning alot here.
