Yes,
start adding the bleach now!
It takes a few days for things to clear up, so the sooner you start adding, the sooner you can swim.

remember to add slowly... if you don't have a skimmer that you can pour through, try diluting in buckets of pool water.

sidenote:
regarding test kits... everyone here seems to use them & I do believe Ben when he says that the test strips aren't accurate enough... however, that being said, I have a couple of test kits sitting around & I haven't been able to use them... ( One was a professional kit that the recreation dept director gave us - no directions, the other other two have directions which seem to be conflicting, so I haven't figured out how to use these)..
I use "guess" strips ( as they are referred to on this forum).
I have several types of them & usually use at least two types per test for a "best guess".
So far ( for three years) these have been accurate enough for me. I do also bring my water in for FREE in-store testing as well ( occassionally at two different stores for a comparrison when results seemed a little off from expected... like being told to add 40KG of calcium!)
My regular (choice) of strips does chlorine up to 10ppm, however we often have our chlorine that high ( I use a feeder with pucks), so I also use a strip that measures bromine up to 20ppm...
( btw, my family doesn't mind the cl @ 10ppm... no sore eyes, no health problems & no the liner isn't bleaching... cya is 30 & no the pucks don't seem to make my cya rise... I don't know why my results aren't the "typical" mentioned on this forum)
now I'm guessing that waterbear will argue that these strips should not be interchangeable, however, Observable results are that they are.
chlorine & bromine are from the same family and I have discovered that testing materials for either sanitizer yields the correct results for both... ( mostly using varieties of Aquachem brand test strips).
If pool chlorine is 10ppm it will show that on chlorine guess strip & bromine guess strip... two pool stores confirm results ( one uses drops, the other is computerized testing system).
-- so I guess what I'm saying is that if you can't afford the kit right now before the end of the season ( assuming that you live northernly & are closing the pool within a month or so), you can get some guess strips that will hold you over for the several times a day testings that you need to do right now... however, if you live anywhere near a pool or hot tub store, they usually do free water tests, so please be sure to confirm your results frequently :-)


Good Luck & Happy swimming
