You should still add bleach, because you used up 4 gal of bleach in one day, right? Yesterday you had cl at 7, this morining you added 4 gal of bleach, and now you have cl at 8. Keep adding bleach, your water is beautiful and you want to keep it that way. Take a cl reading at night after the sun goes down, then early in the morning. You can stop adding bleach when the numbers are the same, in other words you are holding the chlorine. You can add 2 cups of borax, and wait at least 2 hours and test again. Bring your ph up to 7.2. You should be proud of yourself - you did it!! All of your other numbers are good. Your alk is a little high, but ok, and if you have any cal hypo shock you could use that to bring up your chlorine because your calcium is low - They say you don't need calcium in a fiberglass pool, but I like to keep mine around 125 because I have a heater, and some other things I've read abuot fiberglass pools.
