I started my conversion from Baqujunk on August 12, before finding this website. My pool store recommended the Zeneca method. I have a 12000 gallon oval AG Hayward 1.5, sand filter.
They had me adjust the ph to 6.8 to 7 then shock with Sun-brite non chlorine shock 42% potassium peroxymonosulfate....wow tho colors were wild. then run the filter for 48 hours and then I had to adjust the ph to 7.2 - 7.8 which it was already.
Changed out my sand.
Shock again with Cal-hyp, 1 lb for every 8000 gallons and run the pump, the shock foam a lot then settled down quickly. I don't have the test kit yet but is on order.....
This morning the pool water looks like watered down coffee.
Using the test strips my FC is Zero but I believe thats from the chlorine bleaching it out
and my shirt has the white spots to prove it.
Alk - 130
Cya - 0
Th - 350
all from the test strips i have.
