    Options for reducing CYA

    I have also had CYA levels over 100, probably about 120. Over the last 6 months of avoiding the use of tablets containing CYA levels have dropped to 60. I started using Calcium hypochlorite and now using just liquid chlorine. My chlorine levels seem to be holding better as well. I assume CYA...

    California Draught, too much CYA, cloudy pool.

    I bought a long lasting cover (7 year) but it is translucent but not blue. I have been fearful of the potential negative effects of the "clear" cover but did not know the extent. I have wondered why covers tend to be blue. Could chlorine be the reason...maybe somewhat but chlorine loss is still...

    California Draught, too much CYA, cloudy pool.

    I am also using a pool cover day and night, adding 1 Gal a night of KemTek 10% to keep the level at about 3-5 ppm. Pool is 18' x 38' as well with a 7.5' deep end; I figure about 25,000 gal. I found KemTek at Orchard Supply on sale for $5/2 Gal and bought about 50 gal to be used in the next 1-3...

    California Draught, too much CYA, cloudy pool.

    Thank you for the input. How much chlorine is normal for a 25,000 gallon pool sitting at 86°F in the California sun? When the pool was new (15 years ago) I remember putting in chlorine about once a week!

    California Draught, too much CYA, cloudy pool.

    I switched from 3" tablets last year due to high CYA levels. I switched to Calcium Hypochlorite (shock) that results in keeping the algae at bay but the calcium, I assume clouds the pool. This year I have switched to liquid chlorine (for about 1 month now) but because of the high CYA levels, I...

    Cloudy water after 4 days of filtering.

    I also have a cloudy pool because I have been using Calcium Hypochlorite to chlorinate the pool due to high CYA levels already present. My sand filter does not do a good or quick job of filtering out the calcium component. I have gone over to liquid chlorine exclusively for the last two weeks...

    Which pool cover is the best to reduce chlorine loss?

    I had been using the 3 year typical life "blue" bubble cover but most recently bought a longer life (5-7 year) clear cover and it is holding up fairly well after 2 years in northern California. Is the one any better than the other for loss of chlorine? Has anyone ever measured this with...

    Chlorine Date Code Decoder/Easy Way to Measure Strength.

    I describe a way to measure purchased (aged) Chlorine with a simple test kit if you do not have a syringe as described above: Take a used up OTO 1/2oz empty container, wash it out with distilled water several times. (you can pop out the eyedropper from these bottles). Fill the bottle to the...

    Chlorine Date Code Decoder/Easy Way to Measure Strength.

    OK, love the info but I just bought HTH 10% from Wallmart and the only stamping on the box is "C2274" as the lot number. Is there any way to figure out the age from this lot number? I would measure it in an instant with the test method but where do I get an insulin syringe? Also, once you put...

    Help with CYA levels

    Re: what's so bad about high CYA levels? I have a Taylor K1005 but it does not test CYA. The FC ranges from 1-3 after I add 2 gallons of 10% chlorine to the 25,000 pool and spa. The PH is 7.2 and getting a little higher after adding 5lbs of Soda ash. The Total Alkalinity is 200 according to the...

    Dead algae settling overnight after SLAM?

    Misery loves company. I also have been fighting high CYA levels (~140) with massive amounts of liquid Chlorine but I find that the FC is still at 0 every morning after putting in 1 gallon per day now but putting in over 16 gallons over the last week or two. I was using Leslie's granular chlorine...

    Help with CYA levels

    I stopped using Leslie's granular chlorine with stabilizer weeks ago and have only been using liquid chlorine and Power Powder, a calcium hypo. I will change water when California gets some more water. I'm stuck now until at least the Winter rains. It's too bad no one make a CYA reducer. Iadd a...
