    How preccisely do you meeasure bleach?

    Trying to figure out just how precisely I have to measure when adding bleach according to Pool Math. For example, PoolMath says I need to add 172 oz and I have 121-oz bottles and 64 oz bottles. Can I just add one 121-oz bottle and guesstimate how much I need from a 64-oz bottle to reach 172 oz? or do I need to use a measuring cup to measure precisely? Is there some other short cut?

    I just use a 64 oz water pitcher with marking every 8 oz. If I need 20 oz of bleach I fill it half way between the 16 and 24 oz markings. Close enough for Government Work for me.

    Many owners do exactly what you are doing. I took a 30 oz bottle and put marks on the side at at 8, 16, 24 & 30 oz. it gets me close enough if I have to add bleach.

    I use a clear plastic measuring cup.

    Works for me. I add around 32oz of bleach every day.

    Let common sense and pool size dictate your need for accuracy.

    Certainly you can be pretty liberal in a VERY large pool and need to be more precise in a small pool.

    The FC test teach is done in .5 ppm, you can use pool math and figure out just how much that will be in your particular pool and use that as a guideline. There is no sense in being more precise than you can measure.
