I agree, to retro-fit ozone is no problem i can only imagine a communication problem when the tub was ordered. I am sure your dealer will put things right. We are considering a summit siganture off the floor with no onzen/ozone system. Was told to retrofit would cost $1600. Is itit really that costly and is it necessary? we are knew to tubbing and wet tested till we narrowed our ssearch to Arctis. The Galcier was nice but the summit has more room. Can anyone help out w/ info here? Thank you! I bought an ozone machine from spa manufacturer for $300 and fitted it in ten minutes so imo $1600 a bit high

Vincent, If you empty the water, then you can use chlorine after bromine. If you don't, then once you put bromine or bromide into the water, then any chlorine that is added will simply convert bromide to bromine -- that is, you can't get it to be a chlorine spa because the chlorine just becomes a shock or reactivator of bromide to bromine. Once a bromine spa (or pool) then always a bromine spa (or pool) until you change the water. Hydrogen Peroxide will dechlorinate the water so you could use it after chlorine without changing the water, but the initial hydrogen peroxide you add will get used up removing the chlorine -- after that, it will remain. However, hydrogen peroxide is not a fast-acting disinfectant at the levels that don't cause irritation in spa water. It is only an oxidizer and is typically used in Baqua/biguanide/PHMB spas. I don't know why technically bromine won't work with N2 which is metal sticks of silver and copper, but perhaps the sticks are designed to release metal ions at a certain rate with chlorine and that they do not do this with bromine. There are other metal ion systems that are compatible with bromine such as Spa Frog. I'll let others comment on how to avoid itch/rash, but would ask you to take a look at this link to determine if your rash is a chemical sensitivity or if it is bacterial in nature (i.e. hot tub itch). Richard Thanks richard for the link and your reply, I read the link. not really suffering rash just itch now, could have called it a rash a month ago. We spend aprox 1 hour in spa most evenings. usually start to itch about 3 - 5 hours after exiting spar, and not every night. Have noticed dry skin on and about legs, back and arms. get over it by next day, sometimes made worst when area gets hot like laying on sheet in bed, the shoulder will start to itch and the nipples are sensitive to bromine now. Maybe we have absorbed to much of either. because the spa is relatively new to us as is the itch we are still getting in. We do not shower after, we tried this and it didn`t help. I did try the moisturiser and that helped the other itch...haha. I live in small country town population 15000 so experteze is just not there. thats why i`m googleing. I do have another interesting question. concerning the ozone thingy. sometimes it makes bubbles and sometimes it doesn`t, I know where it is cause i installed it and the flow from the pipe did not ever create bubbles until i fitted the ozone. When I was running the bromine system it bubbled all the time when the pump was running but with the chlorine its eratic. Its seems to coinside with high chlorine readings or MPS application. just another of a thousand questions.. cheers

Thankyou for replying OK but if you used the mps stuff that doesnt have chlorine how would that go

Does this only happen to me FC level in spa .05, add 2 tbls Potassium peroxy- monosulphate FC level goes up to 2.6 bromine goes from 0 to 3ppm I thought this was supposed to be a chlorine free shock ?

I seem to be getting an itch from the spa. I would like to change from chlorine to Hydrogen Peroxide (HP) I have an ozone thingy and a N2 stick I have a 1000 ltr spa at 37.5 C degrees I have been told to use HP all you do is Balance the spa and then add 90 mls HP 20 mins before use.nothing after.(and that was without the stick and ozone) Q1 say i get in the spa for 1 hour and i leave behind some baddies, the HP I dosed should kill all those baddies should it not.?? leaving the ozone and the stick to keep the water fresh between dips. Q2 IF i did use HP before the dip and then MPS after the dip what effect would the MPS have on the HP. We have a system that is available to us here , its called spa poppits, it is based on HP, I have not seen it mentioned in any posts. They seem to have a complete system happening though it is a bit more expensive. Maybe your not allowed to say brand names, I am not endorsing this system, just wondered why people seem to be ignoring it. for the picky ones yes it does have a chlorine content in the oxidiser. On a previous post I saw that to reduce your chlorine level you can add HP to the spa. IF you were using HP in the spa and added a chlorine shocker, would not the HP just kill the chlorine. signed frustrated and confused and definatly not a spa guru I just had a mind melt.. running the 90 ml theory and then adding MPS after ........HP is already in mps so if you shocked the spa using MPS that should all be compatable Just too many questions...

I would be interested to know why the chem geek didn`t say to use MPS a non chlorine shock product instead of getting all technical, all the stick wanted to know is if he could use it, and if not, then what>

Hi all I read these posts with great interest. I have owed a spa for a few months, started with brominating concentrate and shocking with spa lite from spaguard and 3 weeks later, dumped the water too much chlorine. advised to go to bromine tablets in floater, shock with mps, 2 months later itch started, neally scratched my testicles off they were so itchy. dumped water went to chlorine...no better still itchy. i week later dumped water again and went to N2 stick and ozone machine and lithium hypo, its been a month with this setup and still slight itch arms, back and legs. I am looking into hydrogen peroxide, there is nothing about HP and spas of any detail in this forum. Spa Poppits sell this system. My local chem guy will sell me HP 50% in 5 litre bottles and he has written a direction sheet, basically you put in 90 mls 50%HP 20 mins before each spa....thats it. I have read all lots of these posts with interest. All I want to do is have a spa without all these hassles. "you can use bromine after Chlorine but you cant use chlorine after bromine".!!! why. can i use HP after chlorine , if not WHY not. the negative comments from some are quite vague, "you probably got smell and itch from public pool" and a lot of the times these answers don`t actually answer the question asked. Why dosent the N2 stick work with bromine???? maybe you guys will know, cause our local shop is promoting sales and thats all.
