    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...

    What is the best chlorine product to use?

    I bought some Insta-test strips and verified that my CYA is somewhere in the range of 150 - 200. I KNOW DRAIN THEPOOL. In a few months.

    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...

    Help with CYA levels

    CH is 300 and CYA is 140. That is from Leslie's report yesterday. The only chlorine test that I see Chlorine greater than 3 is when I wait a couple of minutes using the small OTO reagent. I assume because I have to wait for the solution to turn yellow that is because I am actually looking at the...

    Help with CYA levels

    Split by moderator from HERE. Please start a new thread to ask your own questions and not hijack other member's threads, especially 3 year old ones. Thanks, jblizzle My CYA levels are also very high and unfortunately, due to the water shortage and the draught here in California, I cannot dump...

    What's wrong with my pump? Excess noise? (Video included)

    Sounds like a idling diesel! Only noise like that that a motor makes is mechanical, metal on metal. Bearings.

    Recommendations for leak detection in northern California

    I had a leak and suspected the skimmer. Sealed the skimmer but still leaking. I noticed the sight glass on the filter control valve had water in it suggesting that water was leaking out the drain when the valve was in the normal running position. I took off the rotating selector and found that...

    How long does a SWG cell last

    Re: scale buildup in cells of intellichlor IC40, needs frequent acid wash OK, the equipment is reliable but how much power is used by the salt generating system during it's operation. My electric power is $0.35/KWh so if it takes 150W to run for 6 hours a day, that is a cost of $0.32 a day...

    How long does a SWG cell last

    How long doe a SWG cell last. I assume it is supposed to be catalytic only but what is the practical life for a cell? I heard of many people going to salt system/SWG only to go back once they find out the expense of a replacement cell.

    Water's not ready to close but can I cut down on pump running time?

    As long as you keep the FC up you could get by with a couple hours a day just to circulate the water but the SWG unfortunately needs flowing water to generate Chlorine so you might be stuck. If the SWG has a separate and smaller pump dedicated to it, then you can run the SWG the proper amount of...

    Polaris 380, Dolphin, etc

    I do not understand "no booster pump needed". The info from several source seem to conflict. One say it uses the suction side of a pool and another says it needs a pressure side supply. What does it really need? I have a pressure side, dedicated pump and am using a Letro Legend that seems to...

    Maytronics problems: leaks, Electronics, and motor stress cracks

    It sounded too good to be true: a low energy use, smart pool cleaner. It is too good to be true! Maytronics, well known for their robotic pool cleaners isn't perfect.

    What is the best chlorine product to use?

    I have several test kits, one with about 8 reagents (Taylor DPD) but it is pretty easy for me to go to Leslies for the infrequent (no trouble) water chemistry checks. This test kit cannot measure CYA levels. Pool color is improving but cloudiness continues.

    What is the best chlorine product to use?

    Wall Mart is my only price effective option but it is currently $3.24/gallon in the San Francisco bay area, 10% higher than your area. I bought 10 2 packs for my 25,000 gallon pool and hot tub because the CYA levels are currently high and there is an extreme water shortage in California right...

    What is the best chlorine product to use?

    Unfortunately, I dumped 5 lbs directly into the pool without pre dissolving. I was warned 13 years ago by the person that built my pool to not hesitate if the pool needs soda ash because it can quickly destroy the plaster. The sand filter with some diatomaceous earth is filtering out the cloud...

    What is the best chlorine product to use?

    I have been using Leslie's granular chlorine since the pool was new but no have to put too much in w/respect to CYA levels. I am now using liquid chlorine which is actually Sodium Hypochlorite. Will the CYA already in the pool at a high level protect the chlorine and as a result will have high...

    Maytronics 12+ year Robotic Pool Cleaner User - Review (diagnostic but not limited to
