Help!! I don't know who to believe - Chlorine Lock?

[PoolDoc]

So will I be adding 4 gallons a night for about 4 nights?

No, you'll be adding 4 gallons per night, till you can hold a residual. Trying to analytically predict doses like that ends up being a distraction. You might be right -- but you'd still get there just as surely without the prediction.

Or, you might be wrong, and then pause, and come back here asking what to do. That would slow things down for everyone.

Testing and dosing is not so precise -- in the pool biz -- that predictions work especially well. So instead of testing and then dosing . . . . test, then dose, then test and dose so more till you get there. Works every time!

herrmanncr,

I answered this in your thread. It is helpful if you'll keep your information in that thread that you started, because it gets really confusing for those trying to help two different posters within the same thread. I promise that we're looking at yours as often as we are looking here! It doesn't hurt to read other, similar threads, but please keep your pool details in your own thread to make it easier on us.

Thanks!

Janet
