hi all back again . have some green in pool

again thanks too all!!!!

Add a half a box of Borax slowly to the skimmer while the pump is running. Retest it several hours later and add more if needed. It's ok at 7.0 but no lower. As long as you are 7.2-7.8, you are fine. Other than this, I agree with Jan. Time to swim.

i did this morning added half a box will check again next day or 2 thanks
