I have the exact same problem in my hot tub. It looks exactly the same as the picture above. I've moved from chlorine to bromine and still have the same problem. I've been trying the elbow grease method for ages, I just can't get it off and keep hoovering up huge clogs of it floating around. I've been running spa flush every time I change the water, I also have a pool type system with a sand filter, so frequent backwash and rinse etc. I use an non-chlorine shock once weekly. Any helpful suggestions would be appreciated.

Thank you RDspaguy, I appreciate your response. I'm just a bit baffled as other sources show that you can actually add bromine to a chlorine pool, and that chlorine is just converted to more bromine, so it's the dangerous chemical reaction I also don't understand. Thanks again.

Hello there, I wonder if any of you can help me. I've recently had a cedar hot tub installed, along with a sand pump and chlorinator. I was advised to use bromine tablets, but I couldn't find any at the time and bought Chlorine tablets. The tub has been in operation for a month, and when I cleaned it out, there was like a white residue on the walls that I couldn't clear off. I spoke to the manufacturer, that said that it's the chlorine attacking the wood and I need to change to bromine asap. However, my research shows that to change from chlorine tablets to bromine I'd have to have a new chlorinator / automatic feeder installed? Surely this can't be right? Would it not suffice if I wait till all chlorine tablets are dissolved, then rinse the chlorinator before adding the bromine tabs? Hopefully someone on here will know or at least point me in the right direction! Thank you Ellie
