    SWG questions?

    I have been researching possibly going with a salt water generator system in my fiberglass pool. I know it's supposed to be great with fiberglass but I have a question specific to my situation. My poois surrounded by concrete paver stones. Here is a pic from when I first opened this spring.









    I am concerned about salt corrosion of the stones after all I have read about corrosion with concrete pools. Does anyone have any experience with pavers and SWG pools?

    No issues. We have the same setup here in the Southwest Desert. Hot. Salt has not impacted anything in nearly 3 years.

    Good luck.

    Up here pavers see a lot of salt for deicing walkways. I don't imagine the low salinity pool water would be a problem.

    Re: SWG questions?

    Thanks for the responses, I didn't think they would be any problem but wanted to here from people that have them. I am on county water and the CYA is about 60 right out of the tap. I am always fighting to keep it down to manageable levels with my chlorine setup and I think going to SWG system may be a help. I am still researching and trying to find the best system to go with. The Hayward system gets good reviews and I have always had good luck with their products. Anyone want to make a recommendation for an SWG system, for conversion from chlorine.

    Well I ordered the CircuPool RJ-30 Plus today. I hope the changeover goes smoothly when I get it installed. Anyone with this SWG is welcome to jump in with information.

    Tap water has 0 CYA. You will need to get at least 60 ppm CYA in the water to keep chlorine loss manageable.

    Re: SWG questions?

    Mknauss is correct, tap water does not have CYA in it. How are you getting a reading of 60 from it?

    Re: SWG questions?

    I took a sample from my tap and used the CYA procedure in my T-2006 kit and it came out at 60. I did this test because I drained 1/3 of the pool and the filled it back up 4 times in the last 2 weeks, trying to get my CYA down. I will change 1/3 of the water and my CYA will only drop about 10 points. That is why I checked the tap source. I will do another test tomorrow and see if I made a mistake. Regardless I will be switching over to the SWG system with the new CircuPool.

    Re: SWG questions?

    This sounds like testing error.

    Tap water should have no CYA.

    There is no "should not" about it. Tap water 100% definitely has 0ppm of CYA.

    If you get a reading on tap water a second time, test some bottled water to see if you get a reading.

    tap water has no CYA....period. Your test results are in error. I don't know where the error is but I know you have 0 CYA in your water

    Re: SWG questions?

    Does the water look milky out of the tap? Could just be air bubbles.

    Re: SWG questions?

    Try doing the test with just tap water and no reagent to see if your water is just too cloudy to get a good test.

    Also, pour a tiny bit of acid into the cell to clean it. Over time, the black dot becomes clouded by melamine cyanurate .

    Re: SWG questions?

    Well you guys are correct. I tested the tap water again today and it's zero CYA. I don't know what happened when I tested it the first time but I had to have made some kind of mistake. After another 1/3 drain and fill my pool CYA is now down to 50, so I can make the changeover to the SWG when it arrives. I stopped using tablets this year and just use liquid chlorine, so it should stay good until I can get the SWG installed.
