5 minutes once a week is all it takes to keep your water clean and balanced. We advise against changing your chemicals and never use chlorine or bromine as the irons will store in the timber only to be released if your PH fluctuates. This will cause timber discoloration. Your tub will require emptying and refilling with fresh water every three to six months depending on your level of use and dedication to water care. Your tub  is made from a natural product and will leach saps and resins into the water which gives it the beautiful cedar smell but will also give the water a reddish, orange tint which is completely harmless and clean so don’t mistake this for dirty or imbalanced water. Water treatment options available.  Aqua Spa Starter Kit or Simple Silver is recommended.  These options will be discussed at time of purchase.
