I am a new here .the local pool store must of had a excess of cya to get rid of and sold me 16 lbs to put in pool.you know the results.
So after buying enough chemicals to pay their rent, i found this site.
after several partial drain and refills with well water and a TF 100 here are my results
water is now crystal clear
I live in a area with Hard water and have a water softener but it cannot keep up with the rate of water used in the refill.
a few specks that look like rust are on steps where hose discharged ,are they something to try and correct?
