Hello! I am new to the saltwater system. It is my understanding that electricity is used to produce chlorine ions using copper and titanium plates. I just bought a new saltwater/sand filter pump and it isn't producing any chlorine!!!!! My brother said that he thinks it is set up backwards. He said that the water should flow over the titanium plates first and then directly after, hit the copper probes. Our system is set up where the water hits the copper probes, goes through the sand filter, and then hits the titanium plates and then the pool. I don't know if this is a problem, but despite out best efforts and research and water testing, we can't get it to produce chlorine. So, my first question is, is my brother right? Does the water have to hit the titanium plates first and then the copper probe directly after it, or is our setup ok? The next question is, if our setup is ok, why isn't the pump producing chlorine? We are using the Intex Krystal Clear Sand Filter Pump 16" and Saltwater system. Model number CS20110. We have a 24' diameter AG pool that has about 13,500 gallons of water in it. We have tested the salt and it is 3100 parts per million. We also have tested the water and added the proper amounts of Cyn. acid (stabilizer). We have added muriatic acid to fix the alkalinity. Even when we can get the hardness to an o.k. level, the pH to an o.k. level, the alkalinity to an o.k. level, and the stabilizer to an o.k. level, we can't seem to get chlorine. We covered the pool to avoid chlorine loss due to the sun. We live in FL where it is hot and sunny and humid all of the time. Our water is cloudy and because of the lack of chlorine, it is green. I have tried for months to fix this and can't. Please help! I hate to think that I just bought a very expensive pump for nothing. We are spending lots of $$$$ on chemicals just to keep the levels right, and it just isn't working. We have to clean the plates daily and have had it in boost mode forever. It requires based on my manual for the pump to run for 9 hours a day (which means the boost runs for 36 hours). I feel like I don't know what I am doing, but I have followed everything in the manual to the tee. Any ideas?
