    CYA - seems to cloud water?

    OK, after a total refill of our newly reconstructed (Fiberglass lined over gunite) pool, I have been woring at getting my CYA up close to 50. A side effect that I am noting is that as the CYA levels increase, my pool appears more cloudy ... or basically just not as crystal clear (sparkly?) as pure water with lower CYA levels.

    I assume this is normal? Is there a recommended additive of some sort that gets things "sparkly" clear again? or is such additives not recommended?

    my figures (am slowly adjusting as temps are slowly warming up):

    water temp = 62
    CL = 5.0
    CH = 210
    TA = 80
    PH = 7.5
    CYA = 40

    Adding CYA has never made my water cloudy, less clear, or less sparkling.

    Re: CYA - seems to cloud water?

    OK, then bear with.. When I "test" my CYA levels using the TFT Kit, I mix 50% regeant with 50% water .. then start filling my test tube until "I can no longer see the black dot at the bottom ... That is CLOUDY thereby obsucring the black dot .. with clear water, well, obvioulsly you see the black dot no matter how much water is added to the tube. So I guess when I say "cloudy" water, it is just not 'sparkly' clear like with no CYA conditioner added ... I mean I can still see the bottom & the drain ports etc .. it's not like I can't see the bottom or anything - but just notably not "sparkly" like water was w/o the CYA added. thanks.

    Re: CYA - seems to cloud water?

    The water turning cloudy while performing the test is how the test works. I'm a little confused.

    Re: CYA - seems to cloud water?

    When you are doing the CYA test you specifically add a chemical (the test reagent) that is designed to cause the water to turn cloudy when CYA is present.

    You should not be seeing anything similar to that cloudiness in your pool, regardless of CYA additions. If your water is less than sparkling clear, something is going wrong, possibly minor, possibly major, but worth investigating in either case.

    Re: CYA - seems to cloud water?

    my point is that w/o any CYA in the pool at all, the regeant testing solution is obviolusly CLEAR - sparkly clear - as is the pool water ... As I've been slowly adding CYA over the last 6 weeks, that test now becomes CLOUDY in the tube as you fill it - to obscure the black dot ... and I just perceive a similar observation with the pool water ... it is no longer sparkly clear as when CYA was yet added to the water ... but again, not totally CLOUDY .. still looks great ... just no longer 'sparkly' clear. - most noticeable to me in the deep end looking at the drain.

    Re: CYA - seems to cloud water?

    Sounds like something may be trying to start grow in the pool if it is becoming cloudy.

    Raise the FC up to shock level and perform the OCLT to see if that tells you anything.

    Any cloudiness in your pool is totally unrelated to the addition of CYA.

    The solution in the CYA test becomes cloudy only when you add the R-0013 reagent.....there is no R-0013 in your pool.

    Re: CYA - seems to cloud water?

    As you're adding CYA, are you adjusting your minimum FC value upward?

    Re: CYA - seems to cloud water?

    You listed CL above. Do you have measurements for FC (Free chlorine) and CC (combined chlorine)?

    Re: CYA - seems to cloud water?

    I have 1 that is a week old .. Let me get a fresh reading in the next couple of days after my recent additon of CYA "settles". Thanks

    Re: CYA - seems to cloud water?

    Get a new FC reading now. In terms of testing, one won't affect the other. Any recent CYA addition could take a few days to a week to show up on the test.

    Based on what I've read so far, my guess is that your FC level is still too low for the new CYA level. I would try maintaining an FC level 2-3ppm higher than what you were and see if that helps.

    Re: CYA - seems to cloud water?

    Hi guys .. OK, I finally got around to getting the results from my test yesterday. Results:

    FC = 4.0 (after this, I added 82 oz of 8.25% bleach)
    CC = 0
    TA = 90
    CYA = 50 (I finally got this up to 50 - had been 35-40 over last week)
    CH = 220

    Re: CYA - seems to cloud water?

    Your test numbers look good (and you addition of chlorine should bring you up to ~6 ppm)...how does your water look?

    Re: CYA - seems to cloud water?

    Looks decent ... again, just not "sparkly" like it did prior to adding CYA (clear & fresh tap water). Just an observation ... Everyone says it looks great - just my own 'eye' I guess.

    Thanks ...

    Re: CYA - seems to cloud water?

    So after the pool was filled it was sparkly. Then you started adding cya and running the pump it got a little bit cloudier? You may want to clean and inspect your cartridges
