  1. I took the information I found and created a step by step document that fit on a single page. I am pasting it below. There are two areas I have questions on: For TA increasing, what is the formula to know how much baking soda to add? example: X tablespoons for Y gallons = +30 ppm increase. For Shocking, I prefer to use powder versus bleach. What product should I use? Also, how much to use for the initial shock? I am also unsure how often and how much I shock after that? weekly no matter what? Or, a tablespoon after each use, but I have to leave the cover off for 30 minutes if I do that. Here is my step by step. I can attached the document after one last edit to correct any errors. 1. Fill the spa with water using a pre-filter. Then run pumps to circulate water for 10 minutes. 2. Adjust Total Alkalinity (TA) to between 50-70ppm, but no higher than 100. You can raise TA with baking soda. Wait 30 minutes between adding baking soda and re-testing. Wait 30 minutes with pumps running. 3. Adjust pH to between 7.4 and 7.8. If pH is above 8.0, use dry acid to lower pH. If pH is below 7.2, use borax from the laundry aisle to raise pH.. Note: “pH up” will make your TA go up as well. Wait 30 minutes with pumps running. 4. If calcium hardness is below 130 ppm, raise it to 130-150ppm. If it is above 400 then add an anti stain and scale or calcium reducer to the spa. Any number between 130-400 is ok. Wait 30 minutes with pumps running. 5. Add 1/2 oz of sodium bromide per 100 gallons of water (1.25oz for 250G) to create the bromide reserve in the water. Do not use a one step bromine product that is a mixture of dichlor and only a little bit of sodium bromide. It should only contain sodium bromide (and water if in liquid form). Wait 30 minutes with pumps running. 6. Shock by adding either: Unscented liquid chlorine bleach: Per each 100 gallons of spa water add either 2.5 oz (5 tablespoons) if bleach is 5.25% or 2 oz (4 tablespoons) if bleach is 6%. Shock Powder: What product to use and how much? 58.2% Sodium Dichloro-s-Triazinetrione 7. After shocking, allow spa to run with cover off for 2 hours. Then close the cover and allow the spa to come up to temperature. 8. Measure bromine to ensure it is below 10ppm. If over, remove cover and run pumps. 9. Place bromine tablets into the floater and adjust dispenser daily until bromine = 4-6ppm. 10. DAILY until stable: Check your pH and bromine levels once a day until bromine is stable. If pH is not between 7.2 and 8.0 then adjust. WAIT 30 MINUTES If bromine is low add a few tablespoons of bleach and retest until it is above 4 ppm. This should only take a few seconds to happen. Then adjust the floater to disperse more bromine. If bromine is high, remove cover, remove floater, run pumps. Close down the floater to disperse less bromine. 11. WEEKLY - Keep pH between 7.2 -8.0 and if adjustments are made, then shock the spa with bleach. If hardness is above 400ppm, then add anti scale or calcium reducer. 12. MONTHLY - check and adjust TA, then calcium then pH, then shock spa. 13. After 3 months, use spa purge to clean prior to draining. Clean filters. Go back to step 1.
  2. Looks like I have me some reading to do. Thanks, waterbear. Turns out the prior owner had left a jet closed for a long long time. When I opened it, black stuff shot out. Not sure if it is pillow foam material or mold/film. I have something called "spa purge" that he said he ran without the filter each time before he drained it. So I will be doing a fresh drain/fill in the coming weeks. In the mean time, I will do some reading and get that test kit ordered. Between the chemicals I have and the grocery store, I should have a good direction to go in. One review on the taylor 2106 kit said, "Put two tiny caps of dry agent to test Bromine in either 25m or 10m setting. If its pink then there is Total Bromine present. So great, its pink.... no idea if I have 2ppm or 20." I found that odd.
  3. Getting that Alkalinity up took a lot of product. 3 large caps full spread out over 4 hours. About 7 tablespoons. That seems a bit much, and even after that it is still below the 125ppm minimum. So I put in some pH increase that also read to increase alkalinity. After that I was on the low side of 125-150 for alkalinity and just right for pH at about 7.5. I then put in some shock. I then put in a bromine floater with 1 tablet. Going to try it out this evening and see how my skin (and back, ha) feel afterwards.
  4. Great, thanks much. I am filling it up now and will see what sort of water I have to start out with before I add any chemicals. Tub is 250 Gallons. So far, the cold tub looks like: Hardness - 250 ppm Chlorine - 3 ppm free chlorine - 1ppm pH - 6.8 ppm alkalinity - 40 ppm stabilizer - between 0 and 50 pm This is with Clorox brand pool and spa strips.
  5. Yes, his posts are a good read for sure. If he likes the link above, then I will go that route as the novice approach until I learn more. I am not trying to do this on the cheap. I just recall always chasing balanced water with my last hot tub.
  6. I just bought a used 2015 Master Spa Twilight series and need to decide on my approach to water maintenance. It has ozone. My last tub (10 years ago) used chlorine and it had a chlorine smell and left skin feeling dry and itchy. So I was thinking Bromine for this tub. As I researched, my head started to exploded, then I discovered mineral sticks and my head did explode. Can you provide some links to internet pages with hot tub water approaches that does not have a sales influence or very old information? I figure some of this new technology like a copper + zinc ionizer or a mineral stick sitting inside my filter might be a good investment. Here is one example: https://www.swimuniversity.com/hot-tub-mineral-sanitizer/ Seems legit and is what I am leaning towards following. I am learning a lot on this forums, but I am having to paste together various inputs to draw a conclusion from. Thanks.
  7. I believe this is a common sense question that is not brand specific, but I'd like some experienced input from you all. I just purchased a 2015 Master Spa Twilight 67.25. It has two filters. One normal and one with an Eco Pur insert (so a special filter inside of a normal filter). For the hole that the eco pur filter screws into, there is a green plug/restrictor. It has three tiny holes in it that are 1/8" diameter. It cannot be flowing much if any water. Here is a video of it: https://www.youtube.com/watch?v=cTui6vWEcy4 I think this was a factory installed piece to keep debris out of the return before a filter is installed. Only it never got removed at the dealer or at the delivery What do you think? Also, the previous owner used Bromine while the user manual states in bold to not use Bromine with the Eco Pure filter. I intend to use bromine, so I think my next step is ditch this two part filter (on the left in the video) and just simply run two of the one piece filters. Make since?
