In correct chlorine reading?

Thanks Chris... I thought I had been keeping it higher than needed.... the CYA chart for SWG pools doesn’t list a SLAM chlorine target for 50 CYA?
Yes... pool looks good until I brush... then I get. Pale green cloud and a little green blush on some walls in the shade

Just use the non-SWG CYA level to get the SLAM FC level. SLAM FC level is the same for non-SWG and SWG pools. For CYA 50 it is 20.
