Question:Can DMH be transformed to ammonia in a bromine pool?

If the reccomended concentration of active chlorine for a rezidential pool is arround 0.1 ppm why the reccomended level of bromine are 2-4 ppm and not 0.2 ppm?

Does the DMH affect the ORP value in a bromine spa? I ask this question because if it does, a positive answer might have important implications: First of all an ORP meter will permit someone to generate a bromine-DMH table similar to the chlorine-CYA table. It will explain why it may be...

An abandoned pool has often a lot of organic debris. In time this will ferment and it may degrade to acetic acid ++++. Chlorine may react with this resulting in chloroacetate. This is something that no one wants in the swimming pool water.

Since chlorine can slowly oxidise the cyanic acid would a platinum catalytic convertor speedup this reaction to be of any practical use for people with high CYA in their swimming pools? Just wondering.

First of all I want to express my gratitude towards many experts and experienced persons for the time spent for answering our questions. I do have a question regarding the metal stains in pools or spas that are sanitized with bromine. Since bromine is a less powerful oxidizer is it less likely...

I have stumbled on this site: http://www.google.com/patents/US5948315. Any comments?

Can we have a section for swimming pool jokes? I would love to contribute even though I am not a native speaker.

Is the conversion bromine-bromide (under sunlight) affected by pH? What other factors might influence the bromine stability?

I understand that ORP measurements are not reliable for determining the chlorine concentration in swimming pools and spas due to cyanuric acid presence. In case of using bromine for sanitizing a swimming pool or a spa and cyanuric acid is not present, is it then possible to use the ORP...

Recently a specialist installing a pH controller for my swimming pool said that he is only using active oxygen tablets once a week to sanitize spas. The question is: Is it possible to use only the MPS as a sanitizing agent since it is used to oxidize what bromine cannot?

Hello everybody! I am new to the forum and I do not have a spa yet, but I plan to get one. I am reading a lot about the pool chemistry. Few years ago during a trip to Grand Canaria I came across a spa called Dead Sea Spa with high concentration of salt. I think that it might be a good idea to...

We have purchased last year a holiday house in south of France. It came with a swimming pool (10X5X1.5m) - 75m3. The swimming pool is covered by a dome. The water was nice and clear when we bought the house, but sometime later, to my horror it turned into a green swamp. Last year I had no idea...
