I have a balboa system DU-ELTGRD-DCA 50977. It has worked great for 4+ after finding it on a local FB page. Went to sit in it (heated to 100), and about 5 min into the soak, it blew the breaker at the main fuse panel (not the sub panel by the spa). Been flipping the breaker, it runs the heater for about 5 min then blows again. Disconnected the heater from the panel, run the main and secondary pump without blowing. Other than the heater needing to be replaced, could it possibly be the heater pressure or freeze value/sensor causing it to blow? Thanks for any help

Sorry we were on vacation in Yellowstone last week with limited reception. Thank you for the info. No its a older spa, but still runs great. No ozone, but something we may look into. No, I will look up ahh-some asap.

New to the Spa (Hot Tub) scene, have had pools my whole life but having a hard time keeping the chlorine/bromine levels up. I don't want to over do it but need it to be safe of course. I have to add chlorine daily but ran out, using up the bromine that we got with the spa but would like to move away from that chlorine smell. I am considering two other options to replace the chlorine and bromine. First option is iONRx - https://www.ionrx.com/ Second option is Cleanwater Blue - https://www.spadepot.com/Cleanwater-Blue-Spa-Pro-Supplies-Kit-P2667 Third option is Chlorine or Bromine - If this is the most recommended, what regiment should I be doing...... Thanks for your help Anthony
