So for starters you need 30 ppm of CYA in pool asap via granular in a sock hanging in front of a return. Secondly I'm not convinced your TA is correct because a fresh fill won't be that high. Recheck it and the last of the three regents for the TA especially on new testing kits have static interference so you need to wipe the dropper between each and every drop and of course perfectly vertical when the droplets fall off with very little help. Also check the PH and get back here with the results. As per poolmath hit the target for FC with liquid chlorine and do a OCLT to see if all checks out ok.
