Hi, my SWG for both the pool and hot tub are not working. I have told my pool company and they keep ignoring the problem. In the meantime I have been adding chlorine. When I’m away, the pool people add trichlor. Now my CYA is up to 85. I’m going away for a month. The new SWG’s won’t be here until I am gone. I have someone to meet the pool people here, when the new SWG Cells arrive. I don’t know if my pool company will install them right away or not. My question is how should I maintain my pool and hot tub until then. Is all trichlor the same? Other than floating a puck in the water, I don’t know how else to maintain when I am gone.
