There are times when your swimming pool will change colors after adding chlorine or shocking your pool. The colors may vary from green, red, brown, purple or black. The reason behind this color change usually indicates the presence of minerals (metals) in your swimming pool. The chlorine added to the swimming pool oxidizes the metals and will cause a chemical reaction that becomes visible in your swimming pool.

I have a pool problem for a week. It turns purple from Friday afternoon to Monday last week. Is a 10,000 gallons plaster pool that's is indoor. It is a bromine system.Ph was above 10ppm and bromine was 4. By Monday it turns dark purple (I can provide you pictures) after draining the pool and place new water it was fine, lilac color start after we start recirculation and found out that Nitrates were above 200 initially and then after changing the water nitrates are 180ppm. Bromine is not picking up and Ph is 7.6 now

If it is really purple algae the chlorine will get rid of it along with a wire brush. It is probably a purple stain caused by the copper algaecide added over the years to the pool to control algae. Then the alkalinity gets low and you go to raise the ta and the purple line on the pool forms almost instantly. if you can't get it off with a wire brush then it is probably a stain. Some stain treats may lighten it up but really won't take it completely off. the only thing you can do is drain and acid wash.Try the wire brush 1st, the stain treat 2nd and the acid wash 3rd. good luck and keep the ta over 80.thx

Mon - It's certainly worth a try. Metals will have an impact on chemical stability, and this is a problem in many rural areas that have hard water. If you are looking for a better less costly solution to "feel pf water" you might consider converting to a Salt Chlorine Generation system.Reply

After many hrs of searching for an answer to maganese in my rural water. I am currently using your methods. On my way out to brush sides down on pool. The pool above ground 24'x 54". After I waste water out I plan on using a metal trap when adding water back into pool. Will this keep from having reaction to chlorine products? I have used Soft Swim products for last 2 yrs. Way to costly and fought Algea all last summer. Love the feel of the water but HATE the cost and time consumed keeping pool clean!!!Reply

Interesting images and information. I would add that when using a test strip, if you have sequestrant in the water, it won't give you an accurate metal test. You need to use a tester like EZ-DX Digital Water Test Reader which tests for TOTAL metals.Also, the only way to get the metals out of the water is by using CuLator Metal Eliminator and Stain Preventer. It binds the metals onto a polymer inside a bag that goes into the skimmer basket. If you just use Metal Out or Metal Free, you aren't removing the metal from the water only sequestering the metals and the problem will return in a week or two.
