I CAN'T KEEP CHLORINE IN MY POOL!!!!!!!!!!

Postby chem geek » Sat 15 May, 2010 21:47

Do an overnight chlorine test to see how much you are losing at night with no sun on the pool. If you are only losing chlorine during the day, then you probably don't have enough (or any) Cyanuric Acid (CYA) in the water -- this is also known as stabilizer or conditioner. You should have at least 30 ppm and probably around 50 ppm.

The other possibility is that you have CYA in the water, possibly too much, and that your Free Chlorine (FC) level isn't high enough for your CYA level and that algae is growing, even if it's nascent and not yet visible, but it still uses up chlorine. Your FC should be at least 7.5% of your CYA level in a manually dosed pool. You can learn more by reading the Pool School including the Chlorine / CYA Chart that is there.

Well, its obvious that the chlorine is your problem. Maybe you just put a little amount of chlorine or the brand your using is not helping you.. You can also try using different brands and test which is more productive. Try using aquarite.

It is difficult to tell you without getting the rest of what is or is not in your water. Do you have a test kit to see what your level is? We can help once we have a bit more information.

You have 3 types of readings for Chlorine. Total Chlorine, Free Chlorine and Combined Chlorine. So you take a reading lets say Total Chlorine is 2.5 which imho is a good reading, Free Chlorine is at say 2, now you subtract FC from TC which gives you CC and that comes to .5 So if you are reading a difference of less than 1.5 you are in good shape. There are many many more factors to getting, and keeping, your chlorine so that your ORP(Oxidation Reduction Potential) is maintained at around 700-750. Ph should be as close to 7.4 as you can keep it in your pool, a hot tub should be closer to 7.2. Alkalinity should be between 80-120 and hardness as close to 200 as you can keep it. This is a "balanced" system. TA (total alkalinity) PH, and hardness are the most important aspects to focus on. Once you can stablize those, then you will notice stable chlorine levels. Remember one important thing, if you are talking about an outdoor pool and mistakenly think that Cyunaric acid is your friend you are sadly mistaken. The higher the cyunaric acid level the less effective your chlorine. You absolutely must not have to high a level of cyunaric acid. Many places are now having the health authorities actually ban cyunaric acid as a chlorine stabilizer as even at low levels cyunaric acid reduces the effectiveness of chlorine by over %30. If you think you can smell "chlorine" you actually aren't. What you are smelling are "chloramines". Rather than spend the time here to give in depth explanations it's better to "google" for the explanation.
As somenone who deals with public pools on a daily basis I highly recommend that everyone look into installing a salt water system. This is an automated system that will read everything from your ph to your salt levels and adjust accordingly, to maintain a perfect ORP. An electric in line cell will convert the salt, in the water, to chlorine, as needed to maintain the proper level. Good luck.

You sound like you definitely need some stabilizer in your pool to hold on to the chlorine. I was having alot of problems with algae and I was spending a fortune on chemicals. My pool store told me that most of my chemicals were going to waste through evaporation with my fixed returns that were just below the surface of my pool. He told me to replace all my returns with the circulator and WOW - what a difference it made in my pool. I have not had problems with algae for years now and I spend about half as much as I did for chemicals. He said that the circulator is getting my chemicals down to the floor of my pool and throughout the entire pool to work instead of getting wasted off the surface of my pool. They are a low cost item and they paid for themselves the first month with all the savings that I had on the chemical purchases. I would recommend it to all pool owners who want to have more fun and less hassles with their pool. IT worked great for me as well as my friends and family that I recommended it to over the years. :thumbup:

It seems like you have to much Cyanuric acid in your water
What are you using to chlorinate? (stablised chlorine will introduce Cyanuric acid as well)
Have you read all the information in this post? Especially Chem Geek who is very knowledgable
