Im going to fire up my pool this weekend. Since the water is only mid 40's I am going to obviously use bleach for a while. So, if my CYA is 80 the target FC is 6-9. However, once SWCG is active with a CYA of 80 the FC range is 4-6.
1. Do I just let FC slowly drop prior to starting SWCG? I fear I may let it go too far inadvertently. Perhaps I leave the level as-is and then when the SWCG takes over I slowly adjust.
2. This one baffles me, but why would SWCG need less FC than manual? If chlorine is chlorine, why would it make a difference?
