  1. Thanks for your help. Because I really don't think the hot tub is contaminated--I don't want to do a water change already. The test results have always been fine---I think I must have slipped up though last week, perhaps there wasn't as much in as I thought, for a short time. Right afterwards I added more Purox, and the next reading was still fine--so I never did get a 'bad' reading. I shocked it the next day, and used it several times over the weekend with no trouble. That is why I suspect that on the Wed. (before shocking with MPS, ) I had the problem. It was our two friends who woke up with a rash and they were itchy. I was fine. My husband got the same rash he had last year. He has had the skin problem for a couple of months now atleast. The doctor told him it was excema, so I haven't been too worried about him (poor guy). It seems his problem has nothing to do with the tub. I am hoping that. It would seem that I did not put in enough of the 20 Mule Team Borax. Also, what do I add to get Muriatic Acid in there? Crazy question, I know, but I want to be clear. Next refill. I'll use the Gentle Spa substitute as I did last time. Today's readings: FC 3.5 pH 7.0 TA 70 I do the readings usually at the same time each day. I have been aerateing to get the pH to rise, and it is now at 7.4 There seems to be a lot of foam though. This is another new development.
  2. The FC is tested on a daily basis, and I have never missed adding Purox daily. I suspect that for some reason that night, there just wasn't enough left in as we soaked..... I always add in more right afterwards, as well. The tub is 380 gallons. I do have a question for you. We did a water change in March. We gave it a good cleaning, used swirl away, and was able to buy 10 Mule Team Borax. I am not sure if I have 50 ppm Borates!!! How do I measure that? I was not sure about that, so I put in 19 Tablespoons, then a week later put in another 10 tablespoons. I do not have a really high bather load any longer. I am using MPS to supplement only,and had not used it for a couple of weeks, but shocked with purox. I still used enough Purox, I was very diligent. Right now I am lowering the TA, which is 120. Today's reading are FC 3.0 The usual reading before I add more Purox for the day. pH 7.6 CC 1.0 TA 120 (as I said, I am lowering this as I type) CH 120
  3. It has been a while since I've needed your help!! Things have been going quite smoothly with the hot tub, until last week. I had been following the 'plan' quite well and had no trouble at all. My husband has the rash that he had last winter, but I thought it was 'just him'. Last week (Wed) a couple of our friends were over, and the next day they both say that they were very ithcy and had rashes. I did not. My readings were pretty good before we got in, I added Purox afterwards( the same routine that has worked all these months). The only thing I can think of that I did NOT do was add MPS for a couple of weeks beforehand. I had been shocking with MPS weekly, but ran out , so just shocked with Purox. Do you think that the FC was too low by the end of the evening? The TA and the pH were fine just before we got in. I did not check while we were in, but we weren't in as long as usual. Perhaps 1.5 hours or so. I shocked with MPS on Thurs. and was in for quite a while on Sat. and no ill effects.... I feel kind of badly that my friends woke up itchy and scratchy! They called my husband and told him it was the Purox, and they can't come in the hot tub anymore.... I don't believe it was the Purox....but perhaps the 'lack' of it...?

  5. Hi! Just wanted to let you know that we re-filled the tub on the 29th. We added the swirl away, wiped it all out, and refilled. It was rather painless. I followed your instructions, everything went smoothly. Today's test results are: pH 7.4 TA 80 FC 6 CH 150 CC .5 CYA 30 I have switched to Purox, and the TA and pH are holding nicely. The Borates are making the water feel great too. This time, Iadded things more slowly, and I'm getting much better with the testing! Thanks to you, I am much more confident and of course the water in the tub is fantastic. Hope you had a great Christmas, and thanks again for all of your help.
  6. The reason your pH went over 8 is because 75 ppm TA is still too high for you. Your pH is rising from aeration, and a lower TA will help that. If you get your TA down around 60, your pH should be more stable. A TA of 100 will be much worse than 75. I'm still wondering how your TA got so high. Have you been using Baking Soda to clean your spa? If so, I would stop that. You're getting too much in the water, and messing up your balance. Your TA (and pH) should stay realitivly the same, and not go up, if you don't use BK. I don't know either, why the TA went up there, but as of last night it was stable at 75, and the pH wasn't rising too quickly. I am going to continue today to lower the TA. It is a good learning experience for me, as I am testing often and seeing the results rather quickly. I got my new 'shipment' needed for the Taylor Kit, so I am good to go. Soon, we will change the water. Before that though I will test my tap water and let you know, ok?
  7. Yes, when you first fill the tub, use Dichlor. 1 oz (2 tablespoons) should put you at ~12 ppm in a 380 Gal tub. Let the jets run for 30 min. Then check FC, note it, cover and let sit overnight without using it. 24 hours later check FC again. This will give you a good base line. As I said, I'm only using ~25% FC per day with no use. Assuming you'll be this low (and I believe you will), you should be around ~8 ppm FC the next day. Remember to keep track of the Dichlor you use, so you know when you get to ~30 ppm CYA. That would be a total of 3 ounces (6 tablespoons). Afer you add a total of 6 TBS to your tub, you can check CYA to make sure you're around 30 ppm. Then switch to bleach. Also, I forgot, what's your pH, TA and CH coming from your tap water again? You might want to check it to make sure before you fill. You can balance your water the day after you fill, if your tap water's pH isn't too far off. Lastly, did you use a Spa Flush on your last refill? If not, you may want to consider it. It should break up any gunk in your pipes. With your bather loads, it couldn't hurt. Remove your filter before you use that stuff, and soak it overnight in a filter cleaner. If you come up with a good plan before hand, the whole thing should go quick and easy. We've got some nasty weather here, so we have yet to change the water. However the TA was 125 the pH went to plus 8, so I did the add acid, areate, add acid thing......and today, the TA is 75, and the pH was around 7.0 so I aerated for half an hour and the pH jumped back up over 8. Do you think that perhaps I should have left my TA around 100 so as to not get so much pH bounce? I have added more acid, and I'm going to test in an hour or so again.
  8. Well, the fact that you used it makes it a little hard to tell, but it doesn't seem like it's getting much better. I'd just use it, keep an eye on your FC and drain it the first chance you get. You'll be amazed by the feel of the new water. After you refil it do another Chlorine Demand test before you use it. Shock to ~10 ppm FC, and measure again 24 hours later. That will give you a good base line. Then you can keep track of your CD, by doing a test once a week. If you find your CD to be rising too fast, you know to use more chlorine. Do you mean to shock to 10 ppm with Dichlor as I will be using that for the first few days.
  9. Thanks for the help. I've discussed this with my husband and we think that we'll drain it just after Christmas when we're both off work.
  10. The FC today was 4.0. However, I did go in earlier for about 15 min. so... As far as the high bather load, it has settled down somewhat (especially this week) I'd say that it's about twice a week that there is an 'extreme' bather load on average now.
  11. Shock FC to ~12, and use two ounces MPS. Then see what happens tomorrow. If FC is still low, you're getting tired of shocking and you don't mind adding extra Purox to keep up, you could just deal with it until your next water change. You just need to be extra careful about letting your FC drop too low. Also, it may be difficult to make it through the whole winter without needing another water change. I shocked it to 12, and put 50 grams of MPS in (which is almost 2 oz). This is probably quite tiresome for you, but it is helping me greatly!!! I don't mind at all. My daughter is calling me an incompetent mad scientist! LOL I will be careful about the FC. I was getting worried as I am running out of R-0871, but I ordered a new supply. I am hoping that I won't run out before it arrives. I spoke to my husband about a water change, and he is not too keen at all about doing it during the winter. He says it is not good for the hot tub.... (freezing up I guess) But I will wait for a mild day. It won't go above 0 here very often now. I'm sure it will be fine for a while anyway. You don't mind that I keep on asking advice??? I don't want to become a huge nuisance.
  12. Let me make sure I have it correct. Last night your FC was ~12 ppm???. You added 1 oz of MPS, let it run for 15 mins and closed it up. Today your FC is 4.5 ppm. This is a little better, but you still have a high chlorine demand. Are you having problems with foam and/or waterline scum etc.? The chlorine could be working on oils, lotions etc., which take longer to break down. MPS should help this out. You can try doing another shock tonight. i.e. FC to ~12 ppm and add another oz (or two) of MPS. Only let the jets run for 15 min to mix it before covering. I hate to have you keep shocking the tub, but the only way I see to get your chlorine demand down is to keep shocking it, or do a water change. BTW, when did you change your water last? It could be that because you're using the tub so much, you're now ready for another water change. Have you noticed the water to be sluggish? Do the bubbles take a lot longer to dissipate? After I added 10 oz. of Purox and 1 oz. MPS and aerated for 15 min. the FC was 14.5 (it had been 2.0 before adding) Today the FC was 4.5, yep. I am getting some foam only while all jets are full blast, no waterline scum to speak of, just a little (about the same as always), I am looking for a date of when I changed the water, it was in November. We haven't used the tub this week too much at all. The last day we used it was Tuesday. The water does not feel sluggish at all, but perhaps the bubbles take a bit longer to dissipate. Honestly, the water does seem fine, quite nice actually. I will shock it again tonight and see what happens tomorrow.
  13. Each drop in the TA test represents 10 ppm, not 25 ppm. I used the 10mL sample, 5 drops means 125 right?
  14. Yeah, Canada is a special case since Taylor goes through Lowry and tftestkits.com is not allowed to sell directly through Canada -- any Taylor kits have to go through Lowry as the distributor for Canada. You can get Taylor test kits in Canada through Apollo here since they buy from Lowry's and it's not cheap, but at least with a kit they give you a magnetic stirrer for free. Thanks Richard, you saved me a lot of time!! I've ordered what I needed. So, Nitro, I did everything you said last night, and today the FC is 4.5 CC 1.5 pH7.8. I checked the TA and it was not a brilliant red at 100, but with one more drop it was really red, so that makes it 125. Perhaps this is part of the problem? maybe chem geek has an idea....
