![]() ![]() There appears to be a lot of confusion.Īre there any long term cedar tub users who could help put together a safe maintenance routine for wood tubs. I found several posts here where sanitizing methods where degrading the wood, or others had sustained rashes, others afraid to use bleach. I can see that I need to add higher levels after soaking to achieve 1 ppm FC prior to next soak. My concern is that these low amounts suggested by many of the wood tub suppliers will not manage bather load. I plan on another 10-20 ppm FC addition just prior to next refill. So far the wood seems in great shape with no visible degradation. Here is my question, because wood is organic will the CD always remain high? I have begun soaking once again and adding 3 ppm Dichlor after soaks, next day testing to. I recently performed a modified decontamination using a fresh fill with Ahh Some, purged then drained. Then a fresh fill to rim balancing and adding higher levels of Dichlor in stages 10 ppm, next day 10 ppm, then over next few days bringing level up to 5ppm. I have been very leery of super chlorinating the spa due to posts where users encounter wood fiber disintegration. The last 2 years I was using this very low ppm approach with Dichlor, until my wife got the rash and the tub tested positive for pseudomonas. Spa has warned against the use of ozone, Bromime, and mps as hazards to wood tub life expectancy. Roberts Hot Tub told me I would only need 1/2 tsp of Dichlor 2-3x/week. Other tub makers are proponents on ozonation and mps, but is there sufficient sanitation with this approach. ![]() Spa on this forum recommends very low dose Dichlor method below 3 ppm FC coupled with ionizer, same with Roberts Hot Tub recommendations, yet is this enough to safely deal with Bather load. Many have posted that their new tubs are being turned to pulp by ozone/chlorine/Bromine etc. There is no good consensus on how to maintain wood tubs. It was good fortune that I landed here on the forum! Thank you contributors for a good grasp on water chemistry and especially for the Dichlor/Bleach method. I have been through many tub makers manuals, and spoken with the maker of my tub. I have been on a journey through the posts to decipher a proper maintenance routine for wood hot tubs. ![]()
