    New Salt Water In-Ground Pool

    First time pool first time on a web support but your page came highly recommended. Pool has been in for about 3 weeks and I tested the water last night and the CyA is in the 0 category and I wasn't sure if I needed to increase the chlorine generator or not - the FCI, Alk, and pH are in the ok category? The generator is currently set at 20% for the sanitizer output. If I need to increase the sanitizer output, how long do I keep it at 40% before I turn it back down to 20%. Thanks in advance for the help.
    6000 gallon (18' steel tube frame above ground, 48" tall)
    "C" type cartridge filter
    Pump Type : F2000c GPH flow: 2000

    My source water is Well water, with high ammonia, and high iron levels.

    You are going to want to add some CYA. Usually with salt water you want to be between 60 and 80. Otherwise you are going to end up overworking your salt system. Can you post a full set of test results?

    Welcome

    Please post up the specific numbers for all you levels as that will help us better advise you. Also tell us how you got the test results. Please see:
    pool-school/read_before_you_post

    If your CYA is indeed close to 0, it is very likely that the sun is breaking down the FC just about as fast as the SWG can make it.

    Why do you want to increase the SWG output? It almost sounds like you think that would increase your CYA levels.

    Read through Pool School (link in signature and at upper right of page) a few times to get a better feel for the water chemistry and you will find the levels that we recommend (CYA of 70-80ppm for SWG pools).

    How does your water look?

    Those percentages don't mean a whole lot. You put it on the setting that will maintain your FC. I recommend keeping it around 4-5 PPM. Mine runs at 70%. Like Christian said, post your test results. Some tests say you are in range when truthfully you are off.

    The FCI is at at 1, the Alk is at 80 and the pH is at 7.2. The water is very clear and it does sparkle. The liner is very slippery but it seemed better after I vaccummed it. The contractor who put the pool in gave me a 5 minute class on the gnerator and he actually lowed it to 20% before he left so I thought if I needed to increased or decrease one of the chemicals, I would have to use the sanitizer output but I guess not. Glad I asked for help. I'll read the Pool School.

    Sorry I missed the part where jblizzle asked how I am getting my results... test strips...

    Slippery liner is likely a sign of algae.

    Most likely you need to do the shocking process.

    Test strip results are often wrong more times then right. See link in my sig for an appropriate test kit.

    Having an accurate test kit is invaluable for maintaining your pool with a minimum amount of time and expense. I noticed a big difference in my daily chlorine burn off when my CYA is in the 70-80 range vs 50-60 ppm. Consequently I was able to dial back my SWG run time to 25 to 30%. Good info on this site, and if you follow their recommendations you'll enjoy more trouble free pool time. A good test kit is a must.
