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...
