Are you SURE about your cost to run the pump 24/7? Even if your electricity cost is $0.10/kWh. a month is 24x30=720 Hours; Assume your pump is 1KW (Mine is over 3 KW) it uses at LEAST 720KW/month, that's $72/month if your pump is 100% efficient. HOW MUCH IS YOUR ELECTRICITY?

Calculate the electricity cost first before switching to SW. In California, the cost of running the pump for a long enough time to generate the chlorine level required (~8 hours) would cost me about $16/day so I am sticking to using about 1 gallon of liquid chlorine every 2 days for my >30,000...

FIRST, figure out how long you have to run the pool pump(s) and the cost of the electricity to run the pumps. My cost to run the pool circulation and Polaris cleaner is around $1.50/Hr in California so that may be your dominate cost for chlorination. 12 hours can run $18/day or $540/month just...

I do not know if Home depot has made a pricing mistake because the cost of 2 gallons of 10% chlorine is listed for $18.98! Yikes, that's a 45% increase from last years price. Walmart has 1 gallon/ 10% chlorine for $5.46, so I bought 32 gallons for the season. It's looking like a salt water...

I'd love to see an UPDATED cost comparison of the different Chlorine sources available. Home Depot's cost of chlorine locally (SF Bay Area) is around $9/gallon (pack of two for ~ $18). I could not believe the price. Last year it was about $5/gallon. Three years ago, I was buying it on sale at...

I just purchased liquid chlorine from Walmart for $5.46/Gallon and that was much cheaper than Home Depot's in-store price of >$15/2 gallon box in California. Three years ago, I was buying chloring for sale at $2.5/gallon (on sale) from my local Orchard Supply Hardware store. The inflation for...

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...

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...

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...

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!

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...

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...

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...

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...

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.

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...

Re: scale buildup in cells of intellichlor IC40, needs frequent acid wash Sounds good, thanks for the information.

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...

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...

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...

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...

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...

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

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...

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 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.

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...

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...

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. Look at all of the problems users have had with their Maytronics cleaners on this forum. The common problem: "my unit turns on...
