Good morning, I have a Western Red Cedar hot tub. I struggled to keep the water clear. Perhaps I didn't have the ionizer turned up enough. I began using more chlorine which kept the water clear. As a result, the wood began to fail with fur like wood fibers shedding on the inside. I think I now know how to better maintain the water without a ton of chorine thanks to this forum. I have drained the tub and now waiting for it to dry completely. I want to sand the inside to bring it back to original look and feel. My thought is to use a palm sander with 400 grit to remove the layer of "fur". Has anyone had any experience to share here? Much thanks. -Chuck
