I opened last week and have the numbers below. If I use Traditional pool settings in poolcalculator it tells me to up my CH a little. But I am on target for Troublefree pool settings. Is there an advantage of one over the other. Thus far I have only added 12.5%.
15x30 above ground oval approx 12000 gals water. Liquid Chlorine only. TF-100
FC 2.5 drop test
CYA about 45-50 much better than the 100+ I was pushing for the last 2 years. Exchanged a lot of water.
