Just purchase a 27' 52" AG vinyl pool and I have added two 1lb bags of Dichlor 57% with 35% available chlorine. I added that because it came with my pool and was aware that it could raise my cya very quickly. My FC=1, pH=7.8(maybe a little higher), TA=150, and my cya is 0. I have checked the cya two times using my new TF-100 kit and it has yet to even cloud up even a little. Just seeking some advice going forward. Planning on using bleach to maintain my CL level, but was trying to establish a cya level before I started.
