Annnnnnnnnnd we’re off !!!!
First things first you want to add enough 20 mule borax to get the PH to 7.2. This may prove difficult. My own inherited pool after my move took 4 tries as my 6.8 was much much lower. But attempt to raise it per
PoolMathand retest. Once the PH is good, get a CYA sock going targeting 20 for now to make the SLAM a little easier. It will take a day or so for the granules to dissolve but just SLAM for 20 per the
FC/CYA Levels and when it gets there, it gets there.
Now, you will blow through your FC at first and the more frequently you test/add, the quicker the results. You should shoot for every 2 hours but if life gets in the way, do the best you can.
From here on out you’ll also want to brush twice daily. More if you have the time. Aglae grows a biofilm over itself to protect it and the brushing will help the chlorine kill what’s there on the walls. As you stir it up into the water, BOOM. Dead. But it will also eat up your precious FC so keep on the frequent testing/adding.
