Last year with a chlorine block issue the Forum worked me through it and since have been on the BBB method or at least I think . I have only been using Bleach as required to keep my level around 5 ppm . Presently water is perfect as PH is 7.4 Alk 80 and hardness 180. Have no combined chorine . I do have a metal stain issue and need to address and looking at options?

When on 3inch tabs I was shocking every 2 weeks and treating weekly with Backup for Algae . Since on Chlorine bleach should I still be using the weekly Algae treatment of Backup as I have been doing this ? Do I shock and if so what schedule and with my history of chlorine block do you have a recommendation?

Thanks
