  1. Thanks @waterbear . I used the pH down (sodium bisulfite) that I have and it worked to lower TA. I made a venturi aerator that I'm pretty proud of and it did a good job aerating to raise pH. Currently: TA 60 ( I think- see my 2nd question below) pH 7.5 1. Is the dichlor/bleach method perfectly adapted for cedar tubs is there anything I need to do differently? 2. Reading TA- test kit instructions say you measure when it turns to red. My solution goes from green to clear to pink to red (each separated by one drop). Do I take my measurement when it goes from clear to pink or do I add another drop to make it properly red? 3. Does temperature affect of the chemical readings? I only heat my (wood fired) tub when I want to use it. 4. How many days can I spend adjusting pH and TA before I have to sanitize? In other words, is it okay if it takes me 4 days before getting TA and pH adjusted so that I can proceed to the next steps? 5. Borates = Borax? (at least for this purpose) Thanks in advance to anyone willing to help me out.
  2. Thanks Dashmer. Those readings were before I dumped and refilled. Refilled yesterday and ran the circulation pump and turned on the ionizer. Just tested: pH - 7.8 TA - 120 So sounds like I need to lower my pH (w/ pH reducer) and lower my TA. Questions: What is the preferred way to lower TA? My pH reducer contains sodium bisulfate, will that do? I can’t seem to find any of the links that Nitro references in his original post - looking for the TA down guide and the full dichlor/bleach method guide - a point in the right direction is appreciated) You mentioned aerating to affect pH. I don’t have aerating jets, just a circulation pump/filter. Does that do the trick? At what point should I concern myself with the copper level referenced in the ionizer manual (it says, “maintain chlorine or bromine at 2.3ppm unitl copper is at 0.2ppm-0.4ppm”) Will you continue to help me even though I’m completely clueless? If yes, thank you! I really appreciate your time and feedback.
  3. New to cedar tubs. On my third refill and can't get it right. Seems like dichlor/bleach method is the way to go but I installed a clear blue mineral ionizer first. Do I scrap the ionizer or will it compliment the method? Any feedback is welcome. Tried the @ease chlorinator with zero success. Doesn't register any chlorine. Ionizer has been turned off per my local spa guys recommendation. But he also swore the @ease thing was great for cedar tubs so.. just got a TF100 test kit. drained because of so much tannin and test results of: FC .5 CC .5 TC 1 Calcium hardness 250 TA 130 CYA couldn't read, <20 PH 6.8
