Test it two, or preferably three times a day. Killing algae is big, hungry work for chlorine, and you're going to lose a lot of it to the battle. You want to maintain a steady 20 to 25 ppm army in there until they win.
Sunlight (UV rays) will also kill chlorine troops, so make sure you have a good concentration in the evening for night duty. When you do not lose chlorine overnight, you should be done.
If your pump is running, you can test in about an hour after dosing. Check your pH and TA as well.

Oh yeah, I should mention that you'll want to hose off that filter cartridge every day while your algae is dying, too. All that dead algae will clog the filter, and you want to get rid of it. After a few days to a week, you'll need to replace the element.

Yup thats what i plan to do :P

I just tested, Not sure if i was suppose to lol,

Okay when i tested i mixed 1 part pool water with 3 parts distilled water.

And i add 5 drops of the stuff, It turned Red kinda dark, Now it was off the chart cause the chart only goses to 5 ppm and that is yellowish. so instead of multiplying 5 i multiplyed 7 by 4 and got around 28, so right now i think my water is in the 20-28 range, correct?

i think my water is in the 20-28 range, correct?

Perhaps. You could dilute with 5 distilled to 1 pool, and multiply the result by 6. Your test should stay within the yellow range. If your reading is between 3 and 5, then you're correct (18-30).
