dmanb2b said:Not sure I would advise using sodium bromide, even in small quantity I understand will increase chlorine demand. I think it's an option (when your out of options) in pools with high CYA and folks not being able to lower CYA due to water restrictions, but wouldn't you in essence convert the pool to a bromine pool by doing so?
I think the OP will do just fine with chlorine at MA shock level, but that'ts just my opinion and certainly don't have experience using bromine, but recall reading that before I found TFP and was researching pool sanitizers
The bromide is effective regardless of cya level, and helps reach breaking point in a pool high in cya (though much more effective to drain)chem geek said:The sodium bromide is only really helpful when the CYA level is very high in the pool because bromine doesn't get moderated in its strength by CYA. Even then, since one doesn't normally want a high CYA level, a partial drain/refill is usually required anyway.
However, if you don't have really high CYA, then you can readily shock the pool and kill algae quickly. The main problem with the bromine is that once it's in the pool it takes a long time to leave. If you overuse bromine, then the pool is essentially a bromine pool for some time and the bromine is not significantly protected from the UV in sunlight, at least not in the shallow areas of the water.
I disagree. I don't think that sodium bromide is ever a good solution for a home owner maintaining a residential pool. It costs extra, adds complexity, covers up underlying problems, and if not used correctly makes things worse than they were to start with.Mr. Ed said:It's not always the best solution but used in moderation it is a great solution for a Home owner that needs a quick fix so they can use the pool.

Sodium bromide has become popular because so many people have high CYA levels. Sodium bromide can help get some sanitizer into the pool that will be effective even when your CYA level is too high. It is far far better to simply lower the CYA level. If you do that, not only is the current problem solved, but many future problems are also solved.
Sodium bromide can be handy for pool services that only show up once a week as a quick fix that gets around underlying problems. In that context, it does have it's uses. However, the "default" context here, if you don't say otherwise, is the home owner taking care of their own pool. In that context sodium bromide adds complexity and hides the underlying problem of high CYA.
bk406 said:Adding sodium bromide to a chlorine pool essentially turns it into a bromine pool. The idea that the bromine is gone in 24 hours is prety much without merit. As soon as chlorine is introduced into the pool, it converts it back to active bromine. As chemgeek said, it takes a long while to get rid of all the bromine from even just one treatment. Bromine based algecides are not recommended either for the same reason.
The point Jason is trying to make is that while it may be a quick fix for use by pool companies that do weekly maintenance, it's really just a bandaid to fix bigger issues. While circulation is a concern, and can lead to algea growth, the underlying problem is an improperly chlorinated pool. This usually occurs from a over stabilized pool and an improper FC level based on the CYA value. The proper fix is to decrease the CYA, and maintain an FC level compatable with the amount of CYA in the pool. The point is, adding bromine, for the homeowner taking care of his/her pool, is not the answer to algea issues. Keeping the FC levels relative to the stabilizer is the fix.
One other question I have is your assertation that low TA can be a cause of mustard algea. Can you elaborate?
That's too bad, Mr. Ed - I'd hope you reconsider. Differing viewpoints and opinions only adds to the collective knowledge of all the users on this site.Mr. Ed said:...I know what I am doing....just as some of the moderators here do... and we just seem have a difference of opinion on some things. If I'm going to get attacked every time I suggest something that doesn't fit within a moderator or admin's "preference" then I simply choose not to be a part of what's going on. I think that some of the suggestions you guys are making are fantastic...most of them actually....other's are quite tedious and save a home owner neither time nor significant amounts of money. Unfortunately it's quite some time before people that read these types of forums make it into a location like mine (after several other failed attempts of fixing their problems via uneducated Leslie's employees or pool services, and other websites that contain nothing useful at all) and get good help. I really thought I could extend that help to this forum but sadly I was mistaken.
Admin's.... please do what you choose with my account...delete etc. I won't be back!
dmanb2b said:Ed, I'd really hate to see you leave...I really meant no harm by questioning the use of sodimum bromide. I just recall reading over and over that once a Bromine pool, always a bromine pool...hence why I asked. No doubt you have some great experience, and I think I speak for all the Mods as well as Jason...that your advice is welcome. Every so often though you will find we have a certain way of doing things, so agreeing to disagree is not out of the question
not that it couldn't be used but i've never heard this....however I have used monopersulfate (non chlorine) shock to do so.Ohm_Boy said:I really, really, really don't want to step in this, but I think I recall somewhere seeing Sodium Bromide used for Baquacil conversion to Chlorine.
I've seen that. The peroxide used in baq pools activates the bromine, which then breaks down the baq sanitizer. It can let you keep swimming during part of the conversion, but tends to stop working well before the conversion is complete, leaving you with a partial conversion.Ohm_Boy said:I recall somewhere seeing Sodium Bromide used for Baquacil conversion to Chlorine.
When I wrote that bromine only works well for high CYA situations, I didn't mean that it doesn't work unless the CYA is high. As you wrote, it works regardless of CYA level. I meant that it is only really needed when the CYA is high because when the CYA is lower you can shock with reasonable amounts of chlorine. By "works well" I meant in an overall sense balancing against other options such as using chlorine.Mr. Ed said:chemgeek definitely knows his stuff....that's obvious....but testing of the water 24 hours later shows that the bromide isn't present
