I just received my new HS Vanguard spa and I'm not sure which sanitizer to go with. Are more people using one over the other?
thanks
-
I have only been around for 6 months but would say that most use chlorine, I use chlorine (Dichlor with a Trichlor floater). Do a search for threads on this topic, you will see that opinions vary.

On this forum, I'd guess that most use dichlor.
Overall, I'd think bromine use is pretty common.
Plus there are all the other methods that use neither, like Baqua Spa, etc...
Whatever system you use, you'll have advantages and disadvantages.
-
Dichlor good. Bromine yuck. IMO of course!
-
We got started by the dealer on bromine and haven't noticed anything bad about it. Next to no odor, no dryness (yet). Pretty easy. Add to the floater, reserve and heavy shock once a week. I don't even shock every day and when I do it's one or two capfuls. I keep my bromine levels low (except chemical day)(I have ozone) and my water has stayed clear.
Having said all that, I haven't tried dichlor so I can't say if I'd like it better. But I haven't found a negative on bromine yet. I like the idea of not having to shock and leave the cover open every time (which is what I was told you're suppose to do) on the dichlor routine.

For 3-1/2+ months and counting we've had our Marquis Reward with a built-in Spa frog In-line system (http://www.kingtechnology.com/products/products33.htm) using bromine and it's working fine for us. The Reward also has an ozonator so we're able to keep the bromine level down to 2-4 ppm and the water is great. Very little smell, crystal clear water and does a great job of sanitizing. :)
On a weekly basis, I shock with a non-bromine shock and feed the tub Spa Perfect (http://www.naturalchemistry.com/Pool/Storeplus/Store/viewConsumerItems.asp?idProduct=106) to control organics and other materials like shampoo, conditioners, body oils & soap left over from (other people) washing their swimsuits and not rinsing enough. THAT drives me nuts but skimming off the foam and Spa Perfect both seem to help!

I assume you are asking because the dealer gave you a choice? If so, research our old post and see what you find. Plenty of people use both and its easy to switch. Most people use what they were given, by the dealer, which in my case was chlorine and only change if they have reactions. We have heard here of a few people that had reactions to one or the other.

I used Dichlor with an ozinator. It works well. (toss 1/2 teaspoon in per bather after each use, shock once a week).
I used bromine in a floater in my old tub and it was harsh on my skin, plus I didn't feel I was controlling the amount very well. (throw in some tablets in the floater, play with the hole openings, and try to figure out the rate they disolved, and what to do if you had more bathers, less bathers, yada yada yada...always felt like I was sitting in a chemical bath, and the damn floating duck that dispensed the briomine was alwasy floating into me. or into the filter)
I think Dichlor you have more control over it, is less caustic and easier to control. I would start off with dichlor and if you are having a problem after a few months, change out the water and try bromine, but it seems more people here seem to have better luck with Dichlor.
Just my $.02

Dichlor smells and irritates my skin. Bromine works great for me and with the floater, I only worry about filling the tablets once every couple weeks. I take the floater out when I am in the tub, set it near the steps, and put it back when I get out. Very tough to do, but it's worth the pleasure.
-
Dichlor smells and irritates my skin.
I think it all depends on how you use it... We put in dichlor after each use (or in the evening) and by the time we use the tub the next day it has pretty much dissipated and there is NO smell at all. Actually, there's not much chlorine left at all so it's really easy on our skin. This is the biggest reason we moved from bromine. With the bromine floater there's a constant feed of sanitizer and it was REALLY hard on our skin.

How do you use dichlor in a floater?
BTW, I use dichlor.

This may help. It really depends on personal preferences. I like bromine, it's a more effective sanitizer in the environment that exists in a spa.
Try one.......don't like it ......switch.
Good Luck

The dealer gave me both mentioned sanitizers with my Vanguard purchase. I'll go with the dichlor first and see how it goes. Like you folks say, I can always empty, refill and try bromine. Even though I will do some more research on this topic.
Thanks for your time everyone!

If you use dichlor, it doesn't keep a constant residual of chlorine in the spa, which is why you add a bit after each use. In this case, you also can switch on a moments notice to bromine if you chose to without draining.
If you are using bromine as a sanitizer, you'll also have bromine in some form in the spa and you MUST drain and refill if you are going to switch over to dichlor.
Therefore, if you plan to try both start with the dichlor first and see how it goes and that way you can switch to the other sanitizing method without having to drain.

i use bromine and love it.
No odours, no skin rash or irritation yet and the water is crystal clear. It takes all of five min. a week to care for. It is fool proof and great in my opinion.
-
Hi Markus, I think it also depends on what type of chemical dispenser options your spa has. My Jacuzzi has in the inline filter option, so I use the bromine pucks. I also live in Canada, so getting out to do a dichlor dose is a bit of a pain in the middle winter. With this system, I just put a couple of pucks once to twice a week, and let the bromine do it's thing.
Having said that, I would not use granular bromine, because it's a pain to have to buy two bottles (part A & B) when granular dichlor does the trick.
The benefit, that I know of for Bromine, is that even after it's become a bromamine, (attached itself to bacteria), it can still act as a sanitizer, where dichlor can't do that.
Also, dichlor can't be used in a floater, only Trichlor can, which as many have said on this forum before, Trichlor may void your warranty.

Putting in my two cents of course.....sorry all you dichlor peeps and fans of chlorine..I use bromine with a bromine floater..I've been using it since day one which btw fans of the BP is 5 months ago! So..I like it..no need to change if your comfortable with one product!
-

Ummmmmmmm bromine is chlorine...sorry to burst your bubble. But Bromine uses Chlorine to kill bacteria. The only difference between Bromine and Chlorine is you have to keep adding bromine continualy (floater) because the concentration is lower. With Dichlor the concentration is much higher and it acts faster to kill all junk then dissapates quickly so your not soaking in it, unlike bromine which you are soaking in, which is chlorine at a lower concentrate. Oooow that even confused me!!!
-
I agree with Tman. Anyone who does not use chlorine because of the smell is not using chlorine correctly. A major advantage of chlorine is not having to soak in chemicals. With bromine pucks you still have to watch your sanitizer level and need to add after a heavy bather load or continually put more than needed doing slow damage to the underside of a mostly closed spa, let alone having to sit in it. IMO, with dichlor you have solid control.

No bubbles bursting here.....bromine IS NOT chlorine!
Bromine does not use chlorine to kill bacteria. Bromine is more effective at killing bacteria than chlorine is. The reason that chlorine is added (in it's dry form) to many bromine formulas is because it's a better oxidizer than bromine.(once chlorine is added to a bromine system, it turns to bromine) The reason you need to have bromine in a floater is because is dissolves a lot slower than chlorine.
HOCl-------HOBr Not the same!
-
Bromine is more effective at killing bacteria than chlorine is.
I don't believe this to be true. Maybe as effective, but not more effective. Can you elaborate?
-
No problem,
I should have said more effective in a spa.
Bromine is less sensitive to ph swings. At a ph of 7.8 chlorine is about 20% effective. Bromine is about 80% effective at the same ph.
Once chlorine kills bacteria it becomes a chloramine which isn't bactericidal. Bromine becomes a bromamine which is bactericidal.
-
But bromine is highly acidic and will draw down pH especially since it is continually feeding. You also want to keep bromine away from feeding into the equipment area as its low pH is not good for pumps, heaters, etc.
Dichlor is virtually pH neutral so swings are less frequent from the product itself. If you shock weekly, like you would with bromine, chloramines should never be a problem.
-
The fact that bromine is more acidic than chlorine is a plus in my book. A healthy spa will tend to have its ph climb, so a little acid isn't bad.
As far as keeping it away from equipment - Sundance has had brominators built into their skimmer doors for years - no problems. While bromine is acidic it is being diluted by 400-500 gallons of water! If your water is ph 4.0 then you have a problem.
-
A byproduct of Dichlor is cynuraic acid which over time will affect PH. I add baking soda about once a month to adjust PH. The bromine available here is mostly chlorine as an active ingredient, I have heard that real bromine is out there and I have never tryed it. But I can tell you that it was not good when I used bromine in my spa, it was like soaking in a chlorine bath and I had to adjust PH almost every week. The water was cloudy more and if anyone wants the bucket of tabs I have send me postage. The 2 of them, Bromine and Chlorine both rely on the same procedure for killing bacteria and are the only 2 true sanitizers out there.
Those who prefer it (Bromine) usualy end up switching sometime down the road. I used it for one and a half years before I switched and dichlor is alot easier for me. Maybe not you however.
-
For you dichlor fans, do you guys leave your cover open after every use when you add the dichlor or do you cheat? What do you do during an extended absence like 7 - 10 days to keep your spa water from going murky or do you just shock the heck out of it when you get back?
I notice my water actually feels pretty soft and not chemically - Hardness between 100-200. For soft water is it the NaCl that makes the water feel soft or the lack of Calcium or a combination of both? Will the reserve (NaBr) make the water feel softer?
-
I follow the Vermonter's regime, and leave the cover open for only 5-10 minutes. (After usng a tablespoon of dichlor in a SD Max (580 gals) after use.)
All I have to say is that it's great to use the spa the next day with no sanitizer in it at all. I can't think but using pure water is better. :)
Last spa was Br, and we had nothing but problems. YMMV.

If I go for an extended vacation I have several options, 1. Super clorinate (3-4 TBLS) and turn down the heat to 70-80 before I leave. The lower temp will allow the dichlor to stay in the water for several days and the extra quantity will also boost the time it last. I have gone for 11 days and came back to clean water. The ozonator, and I have been using a N2 Cartrige, will maintain your water as long as there is no bathers.
2. Call your buddy and tell him to use your tub a few times when your gone and add this film container full of stuff after you exit.
3. I have 2 boys that don't go on our yearly vacation to warmer climates anymore, and in the summer it's never longer than 10-14 days and with it turned way down it is not a problem.

We have very low hardness here right out of the tap 30-40 PPM I do not adjust it as I was told thats more of a concern for concrete or tile where the water will precipatate calcium out of it. There's nothing in a Hot Tub for water to get Calcium from. SS or acrylic, plastic or even carbon steel has no calcium for the water to work on. So it makes sence not to worry about hardness. I do however use a softener (soft soak) helps my skin stay better, which any kind of water will dry out. Smells nice to. So I can't answer your question, I wouldn't think your bromine reserve would make your water softer though?
