I'm currently SLAMing the pool to treat algae. Once complete I plan to close the pool. In the past (new to TFP this year) I just took a water sample to the pool store and once they ok'd it I closed. For a couple of years I added algaecide but then someone told me its not necessary so I stopped. I didn't notice a difference when opening. I've never shocked before closing and would open with pretty nice looking water (green but no swamp or algae issue).
I'm not sure how to proceed this year. Do I have to let my fc settle back to normal (4-6), test chems (have k2006 kit) then bring up to shock level again, or can I close with my FC still high?
Why does pool school recommend bringing the chlorine back half way to normal? Wouldn't leaving it at a higher level be better to prevent algae?
